A simple and one-pot synthesis of 2,3,4,5-tetrasubstituted 4,5-dihydro-3H-1,4-benzodiazepines
摘要:
2,3,4,5-Tetrasubstituted 4,5-dihydro-3H-1,4-benzodiazepines were synthesized in one-pot by a new sequential Ugi 4CC/Staudinger/aza-Wittig reaction, starting from easily accessible o-azidobenzaldehyde, alpha-amino ketone hydrochloride, isocyanide and carboxylic acid.
