SYNTHESIS OF A POTENTIAL ANTIFEEDANT SESOUITERPENE INTERMEDIATE FROM A NEW TERPENOID A, B-RING SYNTHON BY TANDEM NICHAEL REACTION

摘要

An efficient synthesis of functionalized 6-decalone 16, starting from a dienolate anion 3a via a tandem Michael reaction, is described. 16 could be used as a potential intermediate for synthesis of drimane related sesquiterpenes.
