Abstract

A total synthesis of (+)-Z-deoxypukalide 3 using a combination of Stille and Nozaki-Hiyama-Kishi(NHK) coupling reactions as key steps, is described. During this study a new practical synthesis of the substituted butenolide intermediate 10, based on a combination of RCM and CM reactions from the cyclobutene ester 21 in the presence of 2-methylpropenol was also developed. Attempts to apply the intramolecular NHK reaction to the substrates 8a and 8b containing an ester group adjacent to the reacting aldehyde functionality gave disappointing low yields (<6%) of the corresponding coupled products 9. The synthetic (+)-Z-deoxypukalide 3 was correlated with naturally derived material, and also with pukalide 1, the first member of the furanobutenolide-based cembranoids to be isolated from corals.
