ON THE ISOMERIZATION OF DIALKYL INDAZOLONES TO DIHYDRO-QUINAZOLINONES
Baiocchi, Leandro,Picconi, Giuseppe
, p. 5255 - 5256 (1986)
1,2-dialkyl-3-indazolones isomerize in basic medium to dihydro-4-quinazolinones.These latter, under more drastic conditions, undergo dismutation to 4(3H)-quinazolinones and antranilamides.
