Abstract

Direct catalytic alkynylation of N-unprotected trifluoromethyl ketimines is reported for the first time. A combination of catalytic amounts of diethylzinc and carboxylic acids promoted the reactions under proton-transfer conditions, allowing an unprecedented direct access to N-unprotected α-tetrasubstituted primary amines without additional deprotection steps.
