Abstract
The enantioselective total synthesis of (+)-virantmycin (1) has been a chieved by means of the Sharpless asymmetric epoxidation of allylic al cohol 27 followed by an intramolecular epoxide opening of the exo epox y alcohol 32 which was derived from the endo epoxy alcohol 28. The syn thesis of (+)-1 has established that the absolute configuration of the natural product (-)-1 is shown to be 2R, 3R at the two chiral centers . Further, antiviral activities of the virantmycin analogs were also e xamined against influenza virus. Copyright (C) 1996 Elsevier Science L td
