摘要

Sept-Oct 1986 Synthesis of Pyrido[ 1',2':1,2]imidazo[4,5-b]pyrazines from 2,3-Dichloro- 5,6-dicyanopyrazine with 2-Aminopyridines Toshinobu Suzuki, Yasushi Nagae and Keiryo Mitsuhashi* College of Technology, Seikei University, Musashino, Tokyo 180, Japan Received February 28, 1986 ... Novel synthesis of the title compounds by the facile cyclization between 2,3-dichloro-5,6-dicyanopyrazine and various 2-aminopyridines under relatively mild conditions is described. The reactivity ...
