Synthesis and Assignments of Regioisomeric Cyanoimidazole Esters

Subrayan, Ramachandran P.,Thurber, Ernest L.,Rasmussen, Paul G.

, p. 2641 - 2656 (2007/10/02)

Regioassignments of ethyl cyanoimidazolecarboxylates have been performed by the nuclear Overhauser effect(NOE) studies on the regioisomeric monocyanoimidazoles obtained by the hydrolysis of the esters followed by decarboxylation.Alternately, regioassignment could also be carried out by comparing the chemical shifts of the N-methyl groups.
