Synthetic routes to α,α-disubstituted allylamines have been examined. Racemic compounds were conveniently prepared by thermal Overman rearrangements of primary allylic alcohols with trisubstituted double bonds, but rearrangement of these substrates using

A new route for the synthesis of isomerically pure allyl and propargyl cyanides has been developed.Allylic amines are synthesized from the corresponding alcohols by Mitsunobu or by Overman reaction.Formylation with formic acid derivatives provides N-substituted formamides, which are dehydrated to isocyanides. 1,2-Sigmatropic rearrangement by flash pyrolysis provides the isomerically pure allyl and propargyl cyanides. Key Words: Isocyanide-cyanide rearrangment / Cyanides, allyl- and propargyl-
