A new approach was developed to construct quaternary stereogenic centers bearing nitrogen
substituents in an enantioselective manner. The strategy takes advantage of [1,3]-chirality
transfer from a chiral primary alcohol equivalent through an allyl cyanate-to-isocyanate
rearrangement. This approach was employed in an efficient eight-step synthesis of
the marine natural product, (+)-geranyllinaloisocyanide, in 43% overall yield.
