Li, Shichen; Ren, Jianing; Ding, Chengcheng; Wang, Yishou; Ma, Chen published the artcile< N,N-Dimethylformamide as Carbon Synthons for the Synthesis of N-Heterocycles: Pyrrolo/Indolo[1,2-a]quinoxalines and Quinazolin-4-ones>, Formula: C6H7N3O2, the main research area is pyrroloquinoxaline preparation; aminophenyl pyrrole DMF heterocyclization; indoloquinoxaline preparation; DMF aminophenyl indole heterocyclization; quinazolinone preparation; aminobenzamide DMF heterocyclization.
N,N-dimethylformamide (DMF) as synthetic precursors contributing especially the Me, acyl, and amino groups has played a significant role in heterocycle syntheses and functionalization. In this protocol, a wide range of pyrrolo[1,2-a]quinoxalines I (R = H, Cl, Me; R1 = H, Cl, Me; R2 = H, Cl, F, Br, Me, OMe; R3 = H, Cl, F, Br, Me, CN), II /indolo[1,2-a]quinoxalines III (R4 = H, Cl, Me, CN, etc.; R5 = H, F, Cl, Me) and quinazolin-4-ones IV (R6 = H, 4-Cl, 4-NO2, 5-Fl, 5-Br; R7 = n-Bu, cyclohexyl, Ph, Bn, etc.) were obtained in moderate to good yields by using elemental iodine without any metal or peroxides. N-Me and N-acyl of DMF that participate and complete the reaction sep. through different mechanisms, which displayed potential still to be explored of DMF were considered.
