Chemoselective and Sequential Palladium-Catalyzed Couplings for the Generation of Stilbene Libraries via Immobilized Substrates
(American Chemical Society, 2016-05)
A versatile palladium-catalyzed tandem synthetic sequence to afford E-stilbenes libraries has been developed. Excellent regio- and stereocontrol have been achieved by means of the sequence of Hiyama and Heck cross-couplings. ...
An effective Pd nanocatalyst in aqueous media: stilbene synthesis by Mizoroki–Heck coupling reaction under microwave irradiation
(Beilstein-Institut, 2017-08)
Aqueous Mizoroki–Heck coupling reactions under microwave irradiation (MW) were carried out with a colloidal Pd nanocatalyst stabilized with poly(N-vinylpyrrolidone) (PVP). Many stilbenes and novel heterostilbenes were ...
Síntese de α-metileno-β-lactamas via ciclização intramolecular de n-propiolamidas catalisada por t-BuOK e sua funcionalização via arilação de Heck catalisada por paládio
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2021-04-30)
The present work describes the regio- and stereoselective synthesis of α-methylene-β-lactams through intramolecular cyclization of different N-propiolamides catalyzed by potassium tert-butoxide. The same, in catalytic ...
