A novel and simple method is described for the synthesis of β-thiohydroximates from oximes and 2,3,4,6-tetra-O-acetyl-1-thio-β-d-glucopyranose, which are key intermediates in the synthesis of glucosinolates. The procedure involves the in situ formation of an oximyl chloride from the oxime, using inexpensive bleach, which is then reacted directly under basic conditions with the thioglucopyranose.

olate is considered to be a potential late stage precursor in the biosynthesis of ( R )-2-hydroxy-3-butenylglucosinolate (progoitrin) and 3-butenylglucosinolate (gluconapin) in Brassica . Chemically synthesized [4,5- 3 H](β- d -glucopyranosyl)- 4-pentenethiohydroxamic acid when administered to developing seedlings of Brassicanapus cv Bienvenu was found to be well incorporated into both 2-hydroxy-

The synthesis of [3,4-3H]but-3-enylglucosinolate is described and its role in (R)-2-hydroxybut-3-enylglucosinolatebiosynthesis is discussed. This is the first time radio labelled but-3-enylglucosinolate has been synthesized and its incorporation into (R)-2-hydroxybut-3-enylglucosinolate demonstrated.
