Reaction of 3-Alkanoylquinoxalin-2-Ones with Ammonium Acetate in DMSO – A New Method for the Synthesis of Pyrroles
摘要:
The interaction of 3-alkanoylquinoxalin-2-ones with NH4OAc in DMSO at 105-120A degrees D produced pyrrole derivatives according to a novel [D-2+N+D-2] scheme, while the -(CO)-CH2- fragment of the substituent at position 3 of the quinoxalinones served as the source of two-carbon fragments D(2)-D(3) and D(4)-D(5), and the nitrogen source was NH4OAc.
