Abstract
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.
