Synthesis of novel hypotensive aromatic thiocarbamate glycosides

Abstract

Syntheses of hypotensive thiocarbamate glycosides from Moringa oleifera are described. The route involves, first, the condensation of the sugar moiety with p-hydroxybenzonitrile to give glycoside 2, then subsequent reduction of 2 to the glycosidic benzylamine 3, which is then converted into isothiocyanate 6. Finally, alcoholysis of 6 gives the desired thiocarbamate glycosides.
