DEFUSCIN, A NEW PHENOLIC ESTER FROM DENDROBIUM FUSCESCENS: CONFORMATION OF SHIKIMIC ACID

Article abstract of DOI:10.1016/0031-9422(89)85065-4

Defuscin, a new phenolic ester shown to be n-triacontyl p-coumarate, and (-)-shikimic acid have been isolated from the whole plant of Dendrobium fuscescens Griff.The 1H NMR spectrum of shikimic acid is indicative of the weighted average of its two half-chair conformers, the one with 4-OH and 5-OH in equatorial orientations being the major contributor. - Keywords: Dendrobiu fuscescens; Orchidaceae; defuscin; n-triacontyl p-coumarate; (-)-shikimic acid; conformation.
