Reactions of 4-oxo-1,3-benzoxazinium perchlorates with sodium borohydride

Reduction of 4-oxo-1,3-benzoxazinium perchlorates with sodium borohydride depending on the structure of starting salt and the reaction conditions leads to different products. 2-Alkyl- and 2-phenylsubstituted salts react with sodium borohydride to give 2,3

Some reactions of 2-styryl-4H-1,3-benzoxazin-4-ones with some nucleophiles and electrophiles

2-Styryl-4H-1,3-benzoxazin-4-ones (IIa-e) have been prepared and reacted with benzylamine and hydrazines to give the corresponding 2-(β,β-disubstituted ethylidene)-1,3-benzoxazinones (III and IV).Reaction of IIc with phenylmagnesium bromide gives VI.Compo
