Abstract

Results Wittig Route to Trisporic Acids and Esters. Our choice of a convergent approach to the trisporic acid system was influenced by the need to accommodate both E and 2 configuration at the 9, lO double bond as well as the 13-keto function of the B series. A Wittig reaction of a cyclohexenone moiety with an appropriate side chain appeared to offer an attractive plan for linking two segments represented generically as X and Y. lIC With this in ...
