Aryl-Nickel-Catalyzed Benzylic Dehydrogenation of Electron-Deficient Heteroarenes

This manuscript describes the first practical benzylic dehydrogenation of electron-deficient heteroarenes, including pyridines, pyrazines, pyrimidines, pyridazines, and triazines. This transformation allows for the efficient benzylic oxidation of heteroarenes to afford heterocyclic styrenes by the action of nickel catalysis paired with an unconventional bromothiophene oxidant.

Antiestrogens. 2. Structure-Activity Studies in a Series of 3-Aroyl-2-arylbenzothiophene Derivatives Leading to <6-Hydroxy-2-(4-hydroxyphenyl)benzothien-3-yl><4-<2-(1-piperidinyl)ethoxy>phenyl>methanone Hydrochloride (LY156758), a Remarkably Effective Estrogen Antagonist with On…

In an effort to prepare nonsteroidal antiestrogens demonstrating greater antagonism and less intrinsic estrogenicity than those currently available, a series of 3-aroyl-2-arylbenzothiophene derivatives was synthesized.These compounds were prepared by Friedel-Crafts aroylation of appropriate O-protected 2-arylbenzothiophene nuclei with basic side-chain-bearing benzoyl chlorides followed by removal of the protective groups to provide the desired compounds containing both hydroxyl and basic side-chain functionality.A particularly useful method for the cleavage of aryl methoxy ethers without removal of (dialkylamino)ethoxy side chain functionality elsewhere in the molecule was found to be AlCl3/EtSH.The benzothiophene derivatives were tested for their ability to inhibit the growth-stimulating action of estradiol on the immature rat uterus.Seemingly minor changes in the side-chain amine moiety were found to have profound effects on the ability of the compounds to antagonize estradiol.Analogues having basic side chains containing cyclic (pyrrolidine, piperidine, and hexamethyleneamine) moieties were found to have less intrinsic estrogenicity and to antagonize estradiol action more completely than their noncyclic counterparts.The most effective antiestrogen in the series, compound 44, <6-hydroxy-2-(4-hydroxyphenyl)benzothien-3-yl><4-<2-(1-piperidinyl)ethoxy>phenyl>methanone, elicited a modest uterotropic activity that did not increase with increasing dose.In antagonism of estradiol, 44 exhibited a degree of inhibition surpassing that of tamoxifen at any dose tested.The new benzothiophene antiestrogen was also shown to have high affinity for rat uterine cycloplasmic estrogen receptor and to be an inhibitor of the growth of DMBA-induced rat mammary tumors.

Modular access to heterocycles: Methyl 3-aminobenzo[b]thiophene-2- carboxylate-thiourea linkage or pyrimidine-4-one-2-thione formation

Modular conditions for the formation of thioureas or pyrimidine-4-one-2- thiones connected to the benzo[b]thiophene, benzene and indole structures were performed. A benzo[b]thiophene isothiocyanate derivative was used as a model to study the condensation with simple aromatic amines and amino-l-sorbose derivative. The construction of pyrimidine-4-one-2-thiones using basic conditions afforded efficiently new heterocyclic aromatics, which were further transformed using the alkylated sulfur as a leaving group in palladium-catalyzed cross-coupling reactions.

Enantioselective functionalisation of the C-2? position of 1,2,3,4,5-pentamethylazaferrocene via sparteine mediated lithiation: Potential new ligands for asymmetric catalysis

The s-BuLi-sparteine base combination deprotonated the C-2? position of 1,2,3,4,5-pentamethylazaferrocene 1 and subsequent reaction with a range of electrophiles gave C-2 substituted products in 76-93% yield and ?80% ee. The products could be recrystallised to enrich ee’s to >90%. Resubjection of the initial addition products (?80% ee) to the deprotonation conditions led to a kinetic resolution to give products with >90% ee and superior overall yields compared to recrystallisation for the cases where the electrophiles were Ph2CO, MeI and Ph2S2. Transmetallation of the 2-lithiopentamethylazaferrocene (?80% ee) with ZnCl2 allowed palladium catalysed cross coupling with a variety of C-2 haloaryl, heteroaryl and vinyl groups to give some novel C-2? substituted pentamethylazaferrocene derivatives in 61-77% yield in 80% ee. Potential N,N-chelate ligands were recrystallised to >95% ee. A novel C 2-symmetric bis-pentamethylazaferrocene 10 could be synthesised by an iron catalysed oxidative coupling of the enatioenriched C-2 lithio derivative and in the presence of a PhMe-Et2O solvent mixture proceeded in 97% ee.

Design, synthesis and evaluation of novel, potent DNA alkylating agents and their antibody-drug conjugates (ADCs)

Antibody-drug conjugates (ADCs) incorporating potent indolinobenzodiazepine (IGN) DNA alkylators as the cytotoxic payload are currently undergoing clinical evaluation. The optimized design of these payloads consists of an unsymmetrical dimer possessing both an imine and an amine effectively eliminating DNA crosslinking and demonstrating improved tolerability in mice. Here we present an alternate approach to generating DNA alkylating ADCs by linking the IGN monomer with a biaryl system which has a high DNA binding affinity to potentially enhance tolerability. These BIA ADCs were found to be highly cytotoxic in vitro and demonstrated potent antitumor activity in vivo.
