Stereo-controlled construction of the core structure of peumusolide A (1), alpha-alkylidene-beta-hydroxy-gamma-methylenebutyrolactone, was developed by a combination of regio- and stereo-selective hydroiodination of 2-yn-1-ol and asymmetric reduction of 1-yn-4-en-3-one as the key reactions. By using this protocol, all the four stereoisomers of the analog of 1 were synthesized from the common starting material. (C) 2010 Elsevier Ltd. All rights reserved.
