| Research Abstract |
Sigmatropic rearrangement of allyl cyanate offers an effcient transformation of the allyl alcohols into the allyl amines with high stereospecific manner. We have planned to apply this rearrangement to the synthesis of natural products. Synthetic efforts focused on the synthesis of marine natural products, such as geranyllinaloisocyanide and manzacidins. As a result, the first non-racemic synthesis of geranyllinaloisocyanide, starting with lactic acid methyl ester, has been accomplished by exploiting a sigmatropic rearrangement of allyl cyanate. An efficient synthetic method for stereoselective construction of asymmetric quaternary carbon stereocenters, bearing nitrogen in the form of Boc-protected allyl amines, has been developed. This methodology is employed in the synthesis of marine alkaloids, manzacidin A and C.
