Name: 4-Nitrobenzoic acid. Xiong, J; Wei, X; Wan, YC; Ding, MW in [Xiong, Jun; Wei, Xiao; Wan, Yu-Chen; Ding, Ming-Wu] Cent China Normal Univ, Key Lab Pesticide & Chem Biol, Minist Educ, Hubei Int Sci & Technol Cooperat Base Pesticide &, Wuhan, Hubei, Peoples R China; [Xiong, Jun] Hubei Univ Sci & Technol, Coll Pharm, Xianning 437100, Hubei, Peoples R China published One-pot and regioselective synthesis of polysubstituted 3,4-dihydroquinazolines and 4,5-dihydro-3H-1,4-benzodiazepin-3-ones by sequential Ugi/Staudinger/aza-Wittig reaction in 2019.0, Cited 59.0. The Name is 4-Nitrobenzoic acid. Through research, I have a further understanding and discovery of 62-23-7.

An efficient one-pot and regioselective synthesis of 3,4-dihydroquinazolines and 4,5-dihydro-3H-1,4-benzodiazepin-3-ones by Ugi/Staudinger/aza-Wittig sequence has been developed. The Ugi reactions of 2-azidobenzylamines, aldehydes, acids (or alpha-keto acids) and isocyanides produced the azide intermediates, which were then treated with tributylphosphine or triphenylphosphine to give poly-substituted 3,4-dihydroquinazolines or 4,5-dihydro-3H-1,4-benzodiazepin-3-ones in moderate to good yields by tandem Standinger/aza-Wittig reactions.
