Syntheses of optically active acetylenic analogs of abscisic acid are described. The key step involves the diastereoselective alkylation of the (2S,3S)-butanediol ketal of oxoisophorone, which produces a 3:1 mixture of separable diastereoisomers. The absolute stereochemistry of the analogs was established by conversion to a known derivative and by correlation of ORD data.
