An efficient multicomponent one-pot reaction was developed for the synthesis of α,α-disubstituted
homoallylic hydrazides by treating ketones, acylhydrazines and allyl bromide with
tin powder in tetrahydrofuran under reflux. The reaction proceeds smoothly without
any catalyst under mild conditions to give the corresponding products in high yields.
Key words
tin powder - one pot - allylation - ketones - α,α-disubstituted homoallylic hydrazides
