Recently I am researching about FACILE SYNTHESIS; RECEPTOR ANTAGONIST; EFFICIENT SYNTHESIS; COUPLING REACTION; DERIVATIVES; CYCLIZATION; ACCESS; SERIES; ROUTE; CELLS, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21572075]; 111 ProjectMinistry of Education, China – 111 Project [B17019]. Name: 4-Nitrobenzoic acid. Published in PERGAMON-ELSEVIER SCIENCE LTD in OXFORD ,Authors: Xiong, J; Wei, X; Wan, YC; Ding, MW. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid
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.
