An efficient method for the allylation of chiral acylhydrazones derived from aldehydes has been developed to give the corresponding allylic hydrazides in good yields and diastereoselectivities. The method uses a combination of tin powder and allylic bromide as allylation system, which avoids the use of toxic allylic stannanes while retaining their merits.
Asymmetric allylsilane additions to enantiopure N-acylhydrazones with dual activation by fluoride and In(OTF)3

A mild, convenient, and stereoselective addition of allylsilanes to enantiopure N-acylhydrazones occurs at room temperature upon complementary activation of both the allylsilane and the hydrazone (see scheme; OTf = trifluoromethanesulfonate). The reaction
