Bis-heteroannulation. 15. Enantiospecific syntheses of (+)and (-)-norsecurinine

(-)-Norsecurinine (2a) has been prepared in a stereospecific fashion with the acetylenic oxazole 39 as the starting material. Diels-Alder cyclization of 39 afforded the furano ketone 45 that was transformed in five steps to the butenolide mesylate 52. Tra
