An improved synthesis of cyclic hydroxamic acids from Gramineae

Tays, Kevin,Atkinson, Jeffrey

, p. 903 - 912 (1998)

The boron trichloride sensitive methoxymethyl (MOM) protecting group has been used to efficiently synthesize polymethoxylated derivatives of the benzoxazinone family of cyclic hydroxamic acids. The MOM group allows the unveiling of the hemiacetal at C-2 of these compounds without demethylating ring methoxy substituents, resulting in greatly increased yields.
