Abstract
The addition of chiral 2-propenylphosphonamide anions, generated from the r eaction products of (1R,2S)-ephedrine and 2-propene-1-phosphonyl dichloride , to alpha -substituted cyclopentenones is described. Ozonolysis of the add ition products led to the synthesis of both enantiomers of methyl dihydroja smonate and methyl jasmonate. (C) 2001 Elsevier Science Ltd. All rights res erved.
