A new glucosinolate synthesis

Abstract

The tert-butyldimethylsilyl nitronate derived from 1-nitropropane was condensed with 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosylthiol to yield two geometrically isomeric thiohydroximates; the Z-isomeric form was then converted by conventional procedures into potassium ethylglucosinolate ("glucolepidiin").
