Studies Directed toward Synthesis of the Structure Proposed for Stereocalpin A

Some synthetic efforts directed to the proposed structure of stereocalpin A are disclosed. The stereogenic centers in the aldol unit were installed using the method of Evans and the intermediates obtained through a reliable route helped to reveal that the spectroscopic data reported earlier in the literature for the same structures were either erroneous or irrelevant.
