Abstract

The synthesis of y-4-hydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one, the enantiomer of the natural acetal glucoside GDIMBOA from maize, has been achieved by the double diastereoselective L-glucosylation of racemic ,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one with 2,3,4,6-tetra-O-acetyl-beta-L-glucopyranosyl trichloroacetimidate in the presence of excess of boron trifluoride etherate as promoter as well as protecting and equilibrating agent.
