متن کاملMichael additions of amines to methyl acrylates promoted by microwave irradiation.
A simple and efficient protocol has been developed for the Michael addition of amines to alpha,beta-unsaturated esters under microwave irradiation. Under these conditions there was a significant decrease in the reaction time, increases in the yields and increased purity of the products.
متن کاملMicrowave Irradiation Promoted Reactions of Orthoesters with Carboxylic Acid Hydrazides. Preparation of 1,3,4-Oxadiazoles
Rapid and highly efficient synthesis of 2- or 2,5-substituted 1,3,4-oxadiazoles by the condensation of aryl carboxylic acid hydrazides and orthoesters can be achieved under microwave irradiation using an unmodified commercial over in unsealed vessels.
متن کاملBenzoyl peroxide (BPO)-promoted oxidative trifluoromethylation of tertiary amines with trimethyl(trifluoromethyl)silane.
The benzoyl peroxide (BPO)-promoted oxidative functionalization of tertiary amines under transition-metal-free reaction conditions was developed. Various 1-trifluoromethylated tetrahydroisoquinoline derivatives were prepared by employing this method. It constitutes the first example of direct trifluoromethylation of tertiary amines.
