A catalyst-free one-step synthesis of N-pyrimidinyl amidines from endocyclic enamines and 4-azidopyrimidine (cas 10597-58-7)s

Add time:08/14/2019    Source:sciencedirect.com

Novel N-pyrimidyl amidines of alycyclic acids were obtained in one step from of 4-azidopyrimidines and endocyclic enamines. The reaction mechanism involves [3 + 2]-addition of azide at the double bond followed by cleavage of thus formed 1,2,3-triazoline ring, and a contraction of alicycle.
