SYNTHESIS OF OUDEMANSINS A AND B

Efficient, stereocontrolled syntheses of the antifungal metabolites oudemansin A and B are described.

Syntheses of (+)-Oudemansin and (+)-Epioudemansin Starting from Enantiomerically Pure Precursors; Absolute Configuration of the Naturally Occuring (-)-Oudemansin

The syntheses of the four optically pure methyl (E)-3-hydroxy-2-methyl-5-phenyl-4-pentenoates (+)- and (-)-5 as well as (+)- and (-)-6 were achieved by consecutive methylation and protonation of enolates, starting from (+)- and (-)-4.The esters (+)-6 and
