A straightforward synthesis of both enantiomers of cis- and trans-3-acetoxy-6-hydroxy-α-ionone is described. The title compounds are prepared by resolution of the diastereoisomerically pure racemic 3,6-dihydroxy-α-ionone isomers. The latter process is bas

Three new ionone glucosides named corchoionosides A, B, and C were isolated from the leaves of Corchorus olitorius, commonly called 'moroheiya' in Japanese, together with seven known compounds, an ionone glucoside (6S,9R)-roseoside, a monoterpene glucosid

The epoxides 16 and ent-16, prepared by Sharpless-Katsuki oxidation of 15 in excellent yield and very high enantiomeric purity, were used as synthons for the preparation of (+)-(S)-didehydrovomifoliol (45), (+)-(6S,7E,9E)-abscisic ester 46, (+)-(6S,7E,9Z)-abscisic ester 47, (-)-(3S,7E,9E)-xanthoxin (49), (-)-(3R,7E,9E)-xanthoxin (50), (3S,5R,6S,3'S,5'R,6'S,all-E)-violaxanthin (1), (3R,5R,6S,3'R,5'R,6'S,all-E)-violaxanthin (55) and their (9Z) (see 53, 57), (13Z) (see 54, 58), and (15Z) (see 60) isomers.The novel violadione (61) was prepared from 1 by oxidation with DMSO/Ac2O.By base treatment, 61 was converted into violadienedione (62), a potential precursor of carotenoids with phenolic end groups.

Hatching stimuli, designated as glycinoeclepins, for the soybean cyst nematode (Heterodera glycines) have been isolated by repeated chromatography of the aqueous extracts of dried roots of kidney bean (Phaseolus vulgaris), one of the host plants of the nematode.One of these compounds, glycinoeclepin A, stimulates the hatching and emergence of larvae in vitro in highly diluted aqueous solutions.
