摘要
Acetylenic alcohol 10 was converted successively into silane 11 and phenylseleno carbonate 14. On treatment with Ph3SnH, the latter undenwent 5-exo-digonal radical cyclization, intramolecular hydrogen transfer, and 5-endo-trigonal cyclization, yielding 15. Conversion of the lactone into the lactol benzyl ether 17, carbon-silicon bond cleavage, and regeneration of the lactone carbonyl gave (+/-)-juruenolide C (1).
