Synthesis of optically active cyclohexanone analogs of the plant hormone abscisic acid

The abscisic acid analogs (-)-(4R,5R)-, (+)-(4S,5S)-, and (-)-(4S,5R)-4(1E,3Z)-4-(4-carboxy-3-methyl-1,3-butadienyl)-4-hydroxy-3,3,5-trimethylcyclohexanones (dihydroabscisic acids), and (-)-(4S,5R)-, (+)-(4R,5S)-, and (-)-(4R,5R)-4(Z)-4-hydroxy-4-(5-hydroxy-3-methylpent-3-en-1-ynyl)-3,3,5-trimethylcyclohexanones were synthesized from a common precursor, (-)-(6R)-2,2,6-trimethylcyclohexan-1,4-dione, which was readily prepared by the fermentation of oxoisophorone with bakers' yeast.

Carotenoids and Related Compounds. Part 38. Synthesis of (3RS,3'RS)-Alloxanthin and Other Acetylenes

The all-trans, 9-cis, and 9,9'-di-cis forms of (3RS,3'RS)-alloxanthin have been synthesized, also the 9-cis-isomer of (3RS,6'RS)-crocoxanthin.Perhydrogenation of alloxanthin gives a product with the same optical properties as perhydrozeaxanthin.These resu
