Description / Table of Contents: A Novel Biomimetic Transformation of Chalcone Glycosides to Isoflavone GlycosidesAcetates of chalcone glucosides were oxidatively rearranged by thallium(III) nitrate in CH(OMe)3/, MeOH and the products cyclized with sodium methoxide to isoflavone glucosides. The pterocarpan medicarpin β-D-glucopyranoside (4) was prepared in an optically pure form.

Notes: Acetate von Chalcon-glucosiden wurden mit Thallium(III)-nitrat in CH(OMe)3/MeOH oxidativ umgelagert und die Produkte mit Natriummethylat zu Isoflavon-glucosiden cyclisiert. Das Pterocarpan Medicarpin-β-D-glucopyranosid (4) wurde in optisch reiner Form hergestellt.
