Abstract

Through structural modification of 2-anilinonicotinic acid by isomerization, a new synthon, acid-aminopyridine, is created, and the two original synthons, i.e., the acid-acid homosynthon and acid-pyridine heterosynthon are no longer observed in the newly designed 6-anilinonicotinic acids. The new synthon has a hydrogen-bond strength rivaling that of the acid-acid homosynthon and the acid-pyridine heterosynthon, as suggested by theoretical calculations, which explains its formation.
