Condensation of Embelin 1 with different aromatic acid hydrazides 2 in glacial acetic acid to give N1-5-hydroxy-6-undecyl-pbcnzoaquinone-2- yl)-benzohydrides 3. Reductive cyclization of the product 3 with simultaneous acetylation in situ resulted in the formation of the compound 4 l-N-acetyl-6,7-diacetyl-3-aryl-5-undccyl-4,1,2-benzoxadiazine. In the final step the compound 4 is deacetylated to give the title products 5. The structures of the newly prepared compounds have been confirmed from analytical and spectral data. Some of the compounds exhibited antibacterial and antifungal activity.

The hitherto unreported 2-aryl-6,7-dihydroxy-8-undecyl-4H-1,3,4-benzoxadiazines 4 have been accomplished by deacetylation reaction of N3-acetyl-2-aryl-6,7-di-acetoxy-8-undecyl-4H-1,3,4-benzoxadiazines 3 obtained by the reaction of 2-aroylhydrazino-5-hydroxy-6-undecyl-1,4-benzoquinones 2.

7-Hydroxy-3-aryl-5-undecyl-4,1,2-benzoxadiazin-6H-ones (Va-e) have been obtained by the reaction of embelin (I) with aromatic acid hydrazides(IIa-e).Their structures were confirmed by converting them to the corresponding 3-aryl-5-undecyl-11H--oxadiazinophenazines (VIIIa-e).A possible pathway involving the formation of enamine intermediate (III) and its subsequent cyclisation to V is suggested.
