Title: Short synthesis of the 6,6-spiroketal cores of spirofungins A and B
Author: Dias, LC
de Oliveira, LG
Abstract: Initial efforts toward the total synthesis of the antifungal antibiotics spirofungins A and B are reported. A short and efficient synthesis of the C9-C20 6,6-spiroketal fragments of both compounds is described. This asymmetric approach uses a very efficient alkylation of a lithiated N,N-dimethylhydrazone followed by spiroketal formation under acidic conditions.
