Cyanohydrin glycosides with unusual sugar residues: revised structure of passitrifasciatin.
The cyclopentanoid cyanohydrin glycoside passitrifasciatin was reisolated, and shown to be (1S,4R)-1-(beta-D-gluopyranosyloxy)-4-(6-deoxy-beta-D-allopyran  osyloxy)-2-cyclopentene-1-carbonitrile, using one- and two dimensional NMR spectroscopy, selective acid-catalysed cleavage of the glycosidic linkage of 6-deoxy-D-allose, and optical rotation data.
