An efficient multicomponent one-pot reaction was developed for the synthesis of α-trifluoromethyl homoallylic hydrazides from the reactions of ethyl trifluoropyruvate, hydrazides and allylic bromide with tin powder in the presence of Brønsted and Lewis acid in 1,4-dioxane under reflux. The method avoids the use of toxic stannanes and allows easy operation. The reaction proceeds smoothly under mild reaction conditions to give the corresponding products in good yields.

Key words: one-pot, tin powder, ethyl trifluoropyruvate, α-trifluoromethyl homoallylic hydrazides
