Publikováno v: Chemical Science

This study uses X-ray crystallography, theory and Langmuir isotherm analysis to explore the conformations and molecular packing of alkyl all-cis 2,3,4,5,6-pentafluorocyclohexyl motifs, which are prepared by direct aryl hydrogenations from alkyl- or v

Isothiourea‐catalyzed acylative kinetic resolution of tertiary α‐Hydroxy esters

Autor: Samuel M. Smith, Víctor Laina-Martín, Andrew D. Smith, Mark D. Greenhalgh, Rifahath M. Neyyappadath, Shen Qu

Publikováno v: Angewandte Chemie (International Ed. in English)

A highly enantioselective isothiourea‐catalyzed acylative kinetic resolution (KR) of acyclic tertiary alcohols has been developed. Selectivity factors of up to 200 were achieved for the KR of tertiary alcohols bearing an adjacent ester substituent,

Autor: Steven P. Nolan, Alessandro Bismuto, Massimiliano Curcio, Martin Corpet, Enrico Marelli, Rifahath M. Neyyappadath, Luigi Cavallo, Giulia Buccolini, Yury Minenkov

Publikováno v: ACS Catalysis

A palladium N-heterocyclic carbene catalyzed methodology for the synthesis of substituted, N-unprotected indoles and azaindoles is reported. The protocol permits access to various, highly substituted members of these classes of compounds. Although tw
