The synthesis of a substance with the revised structure proposed for agrocinopin C (I), D-glucos-2-yl sucros-2-yl phosphate, via the hydrogenphosphonate approach to phosphodiesters is presented. Agrocinopin D, related to agrocinopin C by the lack of the fructofuranosyl part of the sucrose moiety, is synthesized via direct formation of hydrogen-phosphonate diesters from appropriately protected monosaccharides and phosphonic acid.
