Abstract
An effective reagent (performic acid) was proposed for the Bayer–Villiger oxidation of glycyrrhetic acid methyl ester to the corresponding oxepan-2-one. The low-temperature (–70°C) reduction of the latter with excess (5 equiv) diisobutylaluminium hydride in CH2Cl2 resulted in the isolation of 3,4-seco-18β-oleane-4(23),9(11),12-triene-3,30-diol as the main product, while the expected (R)-3,4-epoxy-3-isobutoxy-3,4-seco-18β-oleane-11,12-dien-30-ol...
