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

STRAIN AND SELECTIVITY: PARTNERS FOR ORGANIC SYNTHESIS

The development of two new small-ring conjunctive reagents, (E)-2-(hydrohymethyl)cyclopropyl phenyl sulphide and 1,1-bis(benzenesulphonyl)cyclopropane, are reported.The former permits a synthesis of 2,4-disubstituted cyclobutanones and (E)-4-phenylthio-4-

BIFUNCTIONAL CYCLOPROPYL REAGENTS: A TOTAL SYNTHESIS OF 7-E,9-Z METHYL TRISPORATE B

2-Hydroxymethylcyclopropyl phenyl sulfide combined with sulfenylation-dehydrosulfenylation permits a stereo- and chemoselective approach to trisporic acids.
