Synthesis of (+)-fragolide and (−)-pereniporin B via vinylsilane terminated cationic cyclization
摘要:
Enantioselective syntheses of (+)-fragolide and (-)-pereniporin B are detailed. Marino's lactone annulation method was employed to establish relative and absolute stereochemistry at carbon in the bicyclization substrate. Regio- and stereoselective oxidations of tricyclic drimane precursors are described.
