Photoredox Cross-Coupling: Ir/Ni Dual Catalysis for the Synthesis of Benzylic Ethers

Single-electron transmetalation has emerged as an enabling paradigm for the cross-coupling of Csp3 hybridized organotrifluoroborates. Cross-coupling of alpha-alkoxymethyltrifluoroborates with aryl and heteroaryl bromides has been demonstrated by employing dual catalysis with a combination of an iridium photoredox catalyst and a Ni cross-coupling catalyst. The resulting method enables the alkoxymethylation of diverse (hetero)arenes under mild, room-temperature conditions. (Chemical Equation Presented).

Synthesis of Substituted Cyclopropanecarboxylates via Room Temperature Palladium-Catalyzed alpha-Arylation of Reformatsky Reagents

The room temperature palladium-catalyzed cross-coupling of aromatic and heteroaromatic halides with Reformatsky reagents derived from 1-bromocyclopropanecarboxylates provides an exceptionally mild method for enolate alpha-arylation. The method is tolerant of a wide range of functionalities and dramatically shortens many of the existing routes to access widely used 1,1-disubstituted cyclopropanecarboxylate derivatives.

A New Indirect Application of Aggregative Activation: Synthesis of Esters by Cobalt-Catalyzed Carbonylation of Aryl, Heterocyclic, and Vinyl Halides under Atmospheric Pressure

Sun lamp illuminated alkoxycarbonylation of aryl, heteroaryl, and vinyl halides was performed under atmospheric pressure of CO in the presence of a cobalt catalyst in situ generated from Co(OAc)2.Illunination through a Pyrex flask was sufficient to catalyze the reaction.This process avoids the use of Co2(CO)8 and excess CH3I, which were required in the earlier procedure.A SRN1 mechanism is proposed.

General and Practical Potassium Methoxide/Disilane-Mediated Dehalogenative Deuteration of (Hetero)Arylhalides

Herein we describe a general, mild and scalable method for deuterium incorporation by potassium methoxide/hexamethyldisilane-mediated dehalogenation of arylhalides. With CD3CN as a deuterium source, a wide array of heteroarenes prevalent in pharmaceuticals and bearing diverse functional groups are labeled with excellent deuterium incorporation (>60 examples). The ipso-selectivity of this method provides precise access to libraries of deuterated indoles and quinolines. The synthetic utility of our method has been demonstrated by the incorporation of deuterium into complex natural and drug-like compounds.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 4923-87-9, you can also check out more blogs about4923-87-9

Asymmetric Syntheses via Heterocyclic Intermediates, IV. – Asymmetric Synthesis of alpha-Methylphenylalanine and its Analogues by Alkylation of 1-chiral Substituted 4-Methyl-2-imidazoline-5-one

Treatment of 2-isocyano-N-<(S)-1'-phenylethyl>propionamide (3a) with butyllithium or potassium tert-butoxide (-70 deg C, tetrahydrofuran) initially causes metalation and subsequent (at ca. -20 deg C) cyclization to give the anionized 4-methyl-1-<(S)-1'-phenylethyl>-2-imidazolin-5-one (8).This reacts with benzyl or heterobenzyl halides to yield (4S)-4-benzyl- or (4S)-4-heterobenzyl-4-methyl-1-<(S)-1'-phenylethyl>-2-imidazolin-5-ones 9 with an asymmetric induction (d.e. = diastereomeric excess) >>95percent.Hydrolysis of 9 gives alpha-methylphenylalanine or its analogues of type 11 (nearly optically pure) which have been characterized as their N-acetyl derivatives 12.More over, (S)-1-phenylethylamine (2a), the chiral auxiliary compound, is recovered. – With non-benzylic alkyl halides d.e. is much lower (i.e. with allyl bromide 17percent, with cyclohexylmethyl iodide 35percent). – A model concept for the asymmetric induction which also explains the extremely high asymmetric induction with benzyl halides is proposed. – Methods for the synthesis of 2- unsubstituted 4-alkyl-2-imidazolin-5-ones (type 9a, 15-17) and 2-substituted 4-alkyl-2-imidazolin-5-ones (type 18-20) are described. – The X-ray analysis of 4-benzyl-4-methyl-1-(1′-phenylethyl)-2-imidazolin-5-one (9b) shows a) the “phenyl inside conformation” (folded conformation) for the C-4-benzyl group and b) C-1′ fixed in such a way that the hydrogen atom of the phenylethyl group lies in the heterocyclic plane, pointing towards the carbonyl oxygen.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1196-19-6 is helpful to your research. Electric Literature of 1196-19-6

A new,: Substituted palladacycle for ppm level Pd-catalyzed Suzuki-Miyaura cross couplings in water

A newly engineered palladacycle that contains substituents on the biphenyl rings along with the ligand HandaPhos is especially well-matched to an aqueous micellar medium, enabling valued Suzuki-Miyaura couplings to be run not only in water under mild conditions, but at 300 ppm of Pd catalyst. This general methodology has been applied to several targets in the pharmaceutical area. Multiple recyclings of the aqueous reaction mixture involving both the same as well as different coupling partners is demonstrated. Low temperature microscopy (cryo-TEM) indicates the nature and size of the particles acting as nanoreactors. Importantly, given the low loadings of Pd invested per reaction, ICP-MS analyses of residual palladium in the products shows levels to be expected that are well within FDA allowable limits.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 5394-13-8, help many people in the next few years.SDS of cas: 5394-13-8

Toward Soluble 5,10-Diheterotruxenes: Synthesis and Reactivity of 5,10-Dioxatruxenes, 5,10-Dithiatruxenes, and 5,10-Diazatruxenes

The following work presents three general approaches allowing, for the first time, the synthesis of 5,10-diheterotruxene derivatives containing two identical heteroatoms, namely, oxygen OOC, nitrogen NNC, or sulfur SSC. Two of described pathways involve the photocyclization of the corresponding triene 2 as a key step leading to a heptacyclic aromatic system. The third approach is based on the acidic condensation between ninhydrin 14 and benzo[b]heteroole 15. Typical functionalizations of the 5,10-diheterotruxene core have also been presented. In addition, the article discusses the advantages and limitations of the three suggested paths for receiving specific 5,10-diheterotruxene derivatives because the universal method suitable for obtaining molecules with any type of heteroatoms is not known so far.

Design, synthesis, and structure-activity and structure-pharmacokinetic relationship studies of novel [6,6,5] tricyclic fused oxazolidinones leading to the discovery of a potent, selective, and orally bioavailable FXa inhibitor

The blood coagulation enzyme factor Xa (FXa) is a particularly promising target for anticoagulant therapy, and identification of oral small-molecule inhibitors of FXa remains a research focus. On the basis of the X-ray crystal structure of FXa and its inhibitor rivaroxaban, we designed and synthesized a series of conformationally restricted mimics containing a novel [6,6,5] tricyclic fused oxazolidinone scaffold. Intensive structure-activity relationship (SAR) and structure-pharmacokinetic relationship (SPR) studies on this new series led to the discovery of compound 11a: a highly potent, selective, direct, and orally bioavailable FXa inhibitor with excellent in vivo antithrombotic efficacy and preferable pharmacokinetic profiles. Druggability evaluation of compound 11a was undertaken and elicited positive outcomes. All results indicate that compound 11a is a promising drug candidate for the prevention and treatment of thromboembolic diseases in venous and arterial systems.
