Stereoselective Synthesis of Trisporic Acids A and B, Their Methyl Esters, and Trisporols A and B, Hormones and Prohormones of Mucoraceous Fungi

Syntheses of (9E)- and (9Z)-trisporic acids A (1 and 4) and B (2 and 5) and the corresponding methyl esters (7, 10, 8, and 11, respectively) were accomplished via the Wittig reaction of lactol 52 with an appropriate phosphorane.The lactol was prepared by
