摘要：

Chiral alcohols available in both enantiomeric forms have been tested for the diastereoselective photochemical deconjugation of 2,4-dimethylpentenoic acid esters. (R)-Pantolactone afforded selectively the (2R)-beta,gamma -unsaturated ester in good yield and high d.e. (89%), while analogous use of (S)-pantolactone gave the (2S)-stereoisomer with similar selectivity. (C) 2001 Elsevier Science Ltd. All rights reserved.
