New heterocyclic skeletons derived from the aporphine alkaloid boldine
(MARCEL DEKKER INC, 2002)
The abundant aporphine alkaloid (S)-(+)-boldine (1) was selectively nitrosated with sodium nitrite in acetic acid affording 8-nitrosoboldine (2) which was hydrogenated catalytically to give 8-aminoboldine (3). The latter ...
Síntese e estudo físico-químico de 1,3-imidazóis 2,4,5-trissubstituídos derivados de benzocalcogenazóis
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2016-07-29)
In the following work, an unprecedented series of 2,4,5-trisubstituted 1,3-imidazoles were synthesized from 1,2-diketones and aryl aldehydes, targeting the union of two classes of heterocyclic rings, the imidazoles and ...
N-Heterocyclic carbene copper(I) complex-catalyzed synthesis of 2-aryl benzoxazoles and benzothiazoles
(2016)
A new and efficient synthesis of 2-arylbenzoxazoles and benzothiazoles using a copper N-heterocyclic carbene complex is described. In a simple protocol a variety of 2-substituted benzoxazoles and benzothiazoles were obtained ...
