Strategy for contra-thermodynamic radical-chain epimerisation of 1,2-diols using polarity-reversal catalysis

Polarity-reversal catalysis by thiols has been applied to provide an efficient method for the conversion of appropriate 1,2-diols into less or similarly stable diastereoisomers by epimerisation of their acetonides under radical-chain conditions. (C) 2000

Gold-catalysed activation of epoxides: Application in the synthesis of bicyclic ketals

Gold-catalysed generation of diol equivalents from epoxides and their intramolecular reaction with Ca≡C bonds to generate bicyclic ketals is presented. This reaction essentially involves the formation of an acetonide, which subsequently cyclises on the alkyne intramolecularly under gold catalysis conditions. This method could be extended to make optically pure bicyclic ketals. Deuterium incorporation experiments were carried out to ascertain the mechanism of the reaction. Sequential activation of epoxide and alkyne moieties by a gold catalyst in acetone as solvent has been achieved. This strategyhas been employed to synthesise bicyclic ketals from epoxy alkynes.
