The determination of the configuration at (2-24 of the revised structure of oogoniol (19), a sex hormone of the water mold Achlya, was accomplished by the stereospecific synthesis of the model compounds (24s)-stigmast-5-ene-3@, 29-diol (24) and (24R)-stigmast-5-ene-3P, 29-diol (53) which contain the oogoniol side chain. Diols 24 and 53 were prepared from esters 23 and 46-products of the Claisen rearrangement of (23E,-and 232,229)-6~- ...
