✦ Synopsis

The absolute stereochemistry of (+)-ab6CiSiC acid 1) has been deduced as the (S)-configuration (Ia) by applying nills'empirical rule by Cornforth et a12) in 1967. But, Burden et a13) reported that violaxanthin could be converted to (+)-

## Abstract A stereoselective synthesis of (Β±)‐abscisic acid (**7**) is described in which 2‐__cis__ 3‐methylpent‐2‐en‐4‐yn‐1‐ol (**2**) is used to introduce the 2‐__cis__, 4‐__trans__ geometry.

The elucidation of the absolute configuration of (+)-abscisic acid (IX) was of considerable recent research intereet (l-7). In continuation of our previous work on the synthesis of the optically active grasshopper ketone (III) starting from an optically active ketone (I)(g), we have now accomplished
