Concise synthesis of highly substituted benzo[a]quinolizines by a multicomponent reaction/allylation/heck reaction sequence

The combination of the recently developed multicomponent construction of highly substituted 3,4-dihydropyridones with subsequent allylation and intramolecular Heck-type cyclization allows the straightforward construction of benzo[a]quinolizines, a class of polycyclic compounds that- despite their interesting pharmacological and photochemical properties- have little precedent in the literature. After optimization of the individual steps, we used this reliable three-step sequence to generate a small library of diversely substituted benzo[a]quinolizines and various heterocyclic analogs.

Oxalic Diamides and tert-Butoxide: Two Types of Ligands Enabling Practical Access to Alkyl Aryl Ethers via Cu-Catalyzed Coupling Reaction

A robust and practical protocol for preparing alkyl aryl ethers has been developed, which relies on using two types of ligands to promote Cu-catalyzed alkoxylation of (hetero)aryl halides. The reaction scope is very general for a variety of coupling partners, particularly for challenging secondary alcohols and (hetero)aryl chlorides. In case of coupling with aryl chlorides and bromides, two oxalic diamides serve as the powerful ligands. The tert-butoxide is first demonstrated as a ligand for Cu-catalyzed coupling reaction, leading to alkoxylation of aryl iodides complete at room temperature. Additionally, a number of carbohydrate derivatives are applicable for this coupling reaction, affording the corresponding carbohydrate-aryl ethers in 29-98% yields.

Synthesis of 7-oxo-dihydrospiro[indazole-5,4?-piperidine] acetyl-CoA carboxylase inhibitors

Synthesis of oxo-dihydrospiroindazole-based acetyl-CoA carboxylase (ACC) inhibitors is reported. The dihydrospiroindazoles were assembled in a regioselective manner in six steps from substituted hydrazines and protected 4-formylpiperidine. Enhanced regioselectivity in the condensation between a keto enamine and substituted hydrazines was observed when using toluene as the solvent, leading to selective formation of 1-substituted spiroindazoles. The 2-substituted spiroindazoles were formed selectively from alkyl hydrazones by ring closure with Vilsmeier reagent. The key step in the elaboration to the final products is the conversion of an intermediate olefin to the desired ketone through elimination of HBr from an O-methyl bromohydrin. This methodology enabled the synthesis of each desired regioisomer on 50-75 g scale with minimal purification. Acylation of the resultant spirocyclic amines provided potent ACC inhibitors.

Structure-activity studies for a novel series of tricyclic substituted hexahydrobenz[e]isoindole alpha(1A) adrenoceptor antagonists as potential agents for the symptomatic treatment of benign prostatic hyperplasia (BPH)

In search of a uroselective agent that exhibits a high level of selectivity for the alpha(1A) receptor, a novel series of tricyclic hexahydrobenz[e]isoindoles was synthesized. A generic pharmacophoric model was developed requiring the presence of a basic amine core and a fused heterocyclic side chain separated by an alkyl chain. It was shown that the 6- OMe substitution with R, R stereochemistry of the ring junction of the benz[e]isoindole and a two-carbon spacer chain were optimal. In contrast to the highly specific requirements for the benz[e]isoindole portion and linker chain, a wide variety of tricyclic fused heterocyclic attachments were tolerated with retention of potency and selectivity. In vitro functional assays for the alpha1 adrenoceptor subtypes were used to further characterize these compounds, and in vivo models of vascular vs prostatic tone were used to assess uroselectivity.

Dual Gold Catalysis: Bidirectional Processes and Tandem sp3-C?H Insertion Reactions

Various tetrayne systems were converted under dual gold-catalyzed conditions. For symmetric tetraalkynyl-substituted thiophenes, bearing two alkyl-substituted alkynes and two terminal alkyne units, bidirectional cyclizations led to the efficient formation of dibenzothiophene systems. In all cases, selective CH activation of the C?H bond of the alkyl substituent was observed leading to cyclopentane moieties annelated to the newly formed aromatic cores. If two thiophene moieties were tethered over the attached non-terminal alkynes, depending on the length of the connecting alkyl tether, either bidirectional processes or tandem processes can be addressed leading to interesting molecular structures, such as spiro compounds or isolated benzothiophenes connected by a C?C bond. Other electron-rich heterocycles also reacted. While the reactions even worked for some mixed systems, other cases only delivered the products of a mono-cyclization.
