Transition metal catalyzed C−C bond forming reactions are a power tool in synthesis of organic compounds. In recent years, this strategy has been successfully applied to the several isoindolinone scaffolds. This heterocyclic motif is present large variety naturally occurring, as well synthetic, biologically and pharmaceutically active, Due its crucial role number applications, synthetic methodo...

An efficient and one-pot procedure for the synthesis of arylated and stereodefined allylic alcohols has been achieved through zirconium-mediated multicomponent coupling reactions of alkynes, aldehydes (or ketones), and aryl iodides. The subsequent intramolecular Friedel-Crafts reactions of these allylic alcohols catalyzed by Brønsted or Lewis acids afford highly substituted indenes and spiroind...

In this paper we describe new multi-catalysis cascade (MCC) reactions for the one-pot synthesis of highly functionalized non-symmetrical malonates. These metal-free reactions are either five-step (olefination/hydrogenation/alkylation/ketenization/esterification) or six-step (olefination/hydrogenation/alkylation/ketenization/esterification/alkylation), and employ aldehydes/ketones, Meldrum's aci...

A simple and efficient copper-catalyzed one-pot tandem method has been developed for synthesis of benzimidazo[1,2-b]isoquinolin-11-one derivatives via reactions of substituted 2-halo-N-(2-halophenyl)benzamides with alkyl 2-cyanoacetates or malononitrile under mild conditions.

Several Zn b-diiminate reagents were developed and used to mediate regioselective O-acylation reactions of therapeutic agents with anhydrides. Various prodrugs were obtained in excellent yield and high regioselectivity, including derivatives of rapamycin and paclitaxel. Furthermore, the application of regioselective acylation was extended to one-pot reactions between therapeutics and carboxylic...
