Diazotization of Aminopyridines in the Presence of Camphorsulfonic Acid. Synthesis and Some Properties of Pyridinyl Camphorsulfonates

Diazotization of 2-, 3-, and 4-aminopyridines in the presence of both racemic camphor-10-sulfonic acid and its pure enantiomers led to the formation of the corresponding pyridyl camphorsulfonates in moderate yields. Pyridyl camphorsulonates were found to be more reactive in alkaline alcoholysis than...

Description
Summary:Diazotization of 2-, 3-, and 4-aminopyridines in the presence of both racemic camphor-10-sulfonic acid and its pure enantiomers led to the formation of the corresponding pyridyl camphorsulfonates in moderate yields. Pyridyl camphorsulonates were found to be more reactive in alkaline alcoholysis than analogous pyridyl trifluoromethanesulfonates and pyridyl p -toluenesulfonates.
