A REINVESTIGATION OF THE SYNTHESIS OF 1,2-DIHYDRODIAZEPIN-3-ONES FROM PYRONES
Peet, Norton P.,Sunder, Shyam
, p. 393 - 399 (2007/10/02)
The reactions of 5-acetyl-6-hydroxy-4-(4-methoxyphenyl)-2H-pyran-2-one (5) and 4-(4-methoxyphenyl)-2H-pyran-2,6-dione (4) with hydrazine and phenylhydrazine respectively, gave the respective 1-amino-2-pyridones 8 and 11 rather than diazepinones 6 and 10,
