概要

• 論文の詳細を見る

• The reaction of 7-amino[1,2,3] triazolo[4,5-<I>d</I>]pyrimidine (<B>1a</B>) with chloroacetaldehyde gave imidazo[1,2-<I>c</I>][1,2,3]triazolo[4,5-<I>e</I>]pyrimidine (<B>2a</B>) which underwent facile ring opening in dilute hydrochloric acid. The methyl derivatives (<B>2b</B>,<B>c</B>,<B>d</B>) were similarly made from the appropriate triazolopyrimidine (<B>1b</B>,<B>c</B>,<B>d</B>) and chloroacetaldehyde.
