Abstract

... The present paper describes work in which we explore its application to the NH groups of /V-heterocycles. ... Efficient protection of heterocyclic NH groups has been required in a variety of applications, eg in directed ... H-5), 7.92 (2H, d, J = 5 Hz, pyridinium /3-H), 8.70 (2H, d, J = 5 Hz ...
