摘要

Abstract A general protocol for the synthesis of substituted 5-aminotetrazoles by treating cyanogen azide with primary allylamines afforded either by SN 2 or SN 2′ reactions of Morita–Baylis–Hillman acetates of acrylate has been developed. The base-promoted intramolecular cyclizations of these tetrazoles afford highly substituted 2-azidopyrimidin-4 (3H)-ones instead of the expected tetrazolopyrimidinone due to azide–tetrazole ...
