Chemical synthesis of rhynchosporosides.

AbstractChemical synthesis of rhynchosporosides that cause scald diseases in barley has been summarized in this review. The synthesis features two different strategies, namely, two-stage activation and one-pot glycosylation. Comparing with the stepwise synthesis, the one-pot assembly strategy based on glycosyl <italic>ortho</italic>-(1-phenylvinyl)benzoates can highly streamline carbohydrates synthesis, avoiding such problems as aglycone transfer associated with traditional one-pot glycosylation based on thioglycosides.
