Generation of 1-(trifluoromethyl)-1,2-dihydroisoquinolines via a silver(I)-catalyzed reaction of 2-alkynylaryl aldimine with trimethyl(trifluoromethyl)silane
摘要:
A silver(I)-catalyzed reaction of 2-alkynylaryl aldimine with trimethyl(trifluoromethyl)silane is reported. This reaction proceeds efficiently under extremely mild conditions to generate 1-(trifluoromethyl)-1,2-dihydroisoquinolines in good yields. A three-component reaction of 2-alkynylbenzaldehyde, amine, with trimethyl(trifluoromethyl)silane is presented as well. (C) 2013 Elsevier Ltd. All rights reserved.
