action of 2-formyl-4-pyrrolidinopyridine (FPP, 1a) which is a catalyst for the hydroxyl-directedmethanolysis of alpha-hydroxy esters. This species was initially designed to act as a nucleophilic catalyst; however, we have ruled out a nucleophilic mechanism by examining the activity of 6-substituted-FPP derivatives. These compounds are more hindered in the vicinity of the pyridine nitrogen than FPP itself
