Аннотация

An efficient and pot-economic synthetic approach toward N-substituted triazolobenzodiazepines is presented. This efficient one-pot synthesis, involving the reductive amination of 2-azidobenzaldehydes with benzyl/alkyl amines, followed by N-propargylation and intramolecular (3+2) cycloaddition, generates a variety of N-substituted triazolobenzodiazepines in satisfactory yields.
