Abstract

The <i>C</i>-formylation of 1,3-dimethyl-2(3<i>H</i>)-benzimidazolone and 4-methyl-2<i>H</i>-1,4-benzoxazin-3(4<i>H</i>)-one was performed using 1,1-dichloromethyl methyl ether at the Friedel-Crafts reaction conditions. The formylation of 3-methyl-2(3<i>H</i>)-benzoxa- and -thiazolone at the 6-position was carried out by modified Duff's method with hexamethylenetetramine in trifluoroacetic acid.
