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 43percent overall yield.

The first nonracemic synthesis of (+)-geranyllinaloisocyanide, starting with (-)-lactic acid methyl ester, has been accomplished by exploiting a [3.3] sigmatropic rearrangement of allyl cyanate. The synthesis enables assignment of the S configuration of the C(3) isocyano substituted, quaternary stereogenic center in natural geranyllinaloisocyanide.

The first synthesis of the diterpene, 3-isocyano-3,7,11,15-tetramethylhexadeca-1,6,10,14-tetraene (geranyllinaloisocyanide, 1), has been achieved through an allyl cyanate-to-isocyanate rearrangement.The crucial step in this synthesis is in situ transformation of allyl isocyanates into stable allyl acetamides with trimethylaluminium.
