Catalytic asymmetric syntheses of (?)-oudemanisin A and its diastereomer

The first asymmetric catalytic synthesis of (?)-oudemanisin A 1a and its diastereomer 1b has been achieved. The key steps of our strategy involved the asymmetric alkynylation of an unsaturated aliphatic aldehyde catalyzed by Trost's ProPhenol ligand, chemoselective oxidation of the olefinic diol, base-induced ring opening of the lactone, and acylation–alkylation of the ester.

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
