A convenient synthesis of polyfunctionally substituted heterocyclic systems derived from 4-methyl-2h-1,4-benzoxazin-3-one

Article abstract of DOI:10.1080/10426500108040261

Cycloaddition of 2-[(N-phenyl)thiocarboxamido-]-4-methyl-2H-1,4-benzoxazin-3-one (2) to α,β-unsaturated compounds gave spiro pyridine derivatives. Reaction of compound 2 with some halo compounds afforded thiazolidine derivatives. 2-Ethoxymethylenyl-4-methyl-1,4-benzoxazine-3-thione underwent cyclocondensation reactions with some bidentate reagents. Condensed tricyclic systems have been prepared through the reaction of 3-dicyanomethylenyl-4-methyl-2H-1,4-benzoxazine with the appropriate reagents.
