The union of two powerful transformations, directed C–H activation and decarboxylative cross-coupling, for the enantioselective synthesis of vicinally functionalized alkyl, carbocyclic, and heterocyclic compounds is described. Starting from simple

Publikováno v: ACS Catalysis
A simple method for the conversion of carboxylic acids to boronic esters via redox-active esters (RAEs) is reported using copper catalysis. The scope of this transformation is broad, and compared with the known protocols available, it represents the

Significance The combination of two newly emerging methods for chemical synthesis enables access to molecular space that was previously challenging or impossible to access. Thus, a C–H activation of ubiquitous carboxylic acids followed by their dec

An Eco-Friendly Asymmetric Organocatalytic Conjugate Addition of Malonates to α,β-Unsaturated Aldehydes: Application on the Synthesis of Chiral Indoles
Autor: Karla S. Feu, Senthil Narayanaperumal, Anna M. Deobald, Arlene G. Corrêa, Márcio W. Paixão
Publikováno v: European Journal of Organic Chemistry. 2013:5917-5922
Currently, the synthetic community faces the need to ad-dress growing environmental concerns. To lessen the envi-ronmental impact of organic transformations, all conven-tional synthetic methodologies, including asymmetric syn-thetic protocols, should
