A versatile synthesis of 2‐amino‐4<i>H</i>‐pyrido[1,2‐<i>a</i>][1,3,5]triazin‐4‐ones from 2‐aminopyridines

Abstract

Abstract The quasi‐one pot synthesis of new 2‐aminopyrido[1,2‐ a ][1,3,5]triazin‐4‐ones starting from 2‐amino‐pyridine and 2‐aminopicolines is herein described in order to obtain a library of cyclic guanidines.
