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").
