A general strategy was developed to synthesize ω-methylthioalkyl glucosinolates through a coupling reaction between 1-thio-β-D-glucopyranose and a hydroximoyl halide obtained from the corresponding nitroalkyl methylsulfide precursor.
A general pathway was devised to synthesize ω-methylsulfanylalkyl glucosinolates, which represent an important class of structurally homogeneous plant secondary metabolites. The required thiofunctionalized hydroximoyl chlorides were obtained from the corresponding α,ω-nitroalkyl methylsulfide precursors, involving as the key-step, a nitronate chlorination strategy. A coupling reaction with 1-thio-

An isotopically labelled building block, 2,3,4,6-tetra-O-acetyl-1-thio-beta-D-[C-13(6)]glucopyranose (4), is obtained from the commercially available [C-13(6)]-D-glucose. This hexa-C-13-labelled thioglucose can be employed to make any glucosinolate (8) for use as an internal standard for isotopic dilution LCMS analysis. Herein three typical glucosinolates in their hexa-C-13-labelled form: [glucose-C-13(6)]gluconasturtiin, [glucose-C-13(6)]sinigrin and [glucose-C-13(6)]glucoerucin are synthesised by coupling the isotopically labelled thioglucose (4) with the corresponding hydroximoyl chlorides followed by sulfation with pyridine sulfur trioxide and deacetylation with a catalytic amount of potassium methoxide, respectively.
