Versatile Protecting-Group Free Tetrazolomethane Amine Synthesis by Ugi Reaction [PDF]

open access: yesACS Combinatorial Science, 2016
The use of ammonia in the Ugi reaction is often problematic due to low yields and multiple side reactions. Here, we report the use of ammonia in the tetrazole Ugi variation providing a clean, good-to-high yielding reaction, especially with ketones as oxo
