Carbonyl and Thiocarbonyl Compounds: Part XV-Synthesis of Spiro and Quinazolinone Anils

Tetrachloro-o-benzoquinone reacts with 2,3-diarylquinazoline-4(3H)-thiones (4a-c) to give spiro (5).The latter are cleaved with mineral acids to give 2,3-diarylquinazolin-4(3H)-ones (4d-f).Reaction of 5 with anilines affords the hitherto unknown quinazolinoneanils (6) together with tetrachlorocatechol.Reaction mechanisms are discussed.
