The preparation, structure and reactions of some “malonyl‐α‐aminopyridines”

Abstract

Abstract The reaction of several substituted 2‐aminopyridines with diethyl malonate was studied. The “methylmalonyl‐α‐aminopyridines” were shown to exist in the same tautomeric form as “malonyl‐α‐aminopyridine”. Formylation of these compounds takes place in the 3‐position and has led to the formation of a new tricyclic compound.
