Total syntheses and structural revision of α- and β-diversonolic esters and total syntheses of diversonol and blennolide C

Abstract

Expedient total syntheses of the originally proposed structures of the naturally occurring α- and β-diversonolic esters (1 and 2) and diversonol (3) lead to the revision of the structures of 1 and 2 to 4 and 5, respectively (see structures).
