Research Abstract |
Synthesis of platencimycin and bicyclolactone unit of shimalacton possessing sequential quaternary carbons was investigated. In the former, the tri cyclic compound possessing the desired quaternary carbon was obtained with a high selectivity by heating the precursor which consists the diene unit possessing cyclopentane and the dienophile unit possessing tri-substituted alkene at 200℃. In the latter, by utilizing transannular cyclization of the lactone, the cyclopentane derivative was obtained as a sole product with the desired stereochemistry.
