A novel and metal-free sequential Ugi-4CR/alkyne-azide cycloaddition reaction towards the synthesis of new 1,2,3-triazolobenzodiazepinones under a mild reaction is reported. The reaction of (E)-2-(1-alkynyl)-3-arylpropenoic acids, 2-azidobenzenamines, aldehydes, and isocyanides produced 1,2,3-triazolobenzodiazepinones by a Ugi 4CR/alkyne-azide cycloaddition sequence in excellent yields ranging from 77% to 92%. Furthermore, simple operation, high atom economy and good to excellent yields all make it useful in synthetic and medicinal chemistry.

Key words: one-pot, metal-free, Ugi 4CR, alkyne-azide cycloaddition, 1,2,3-triazolobenzodiazepinone
