Tritylamine as an Ammonia Surrogate in the Ugi Tetrazole Synthesis
摘要:
The role of tritylamine is introduced as a convenient ammonia substitute in the Ugi tetrazole synthesis. Fifteen examples and their mild cleavage products are described In satisfactory to good yields. N-Unsubstituted alpha-aminotetrazoles are important compounds with annotated biological activities, and the described two-step synthesis provided an alternative route to otherwise difficult to access derivatives.
