The invention relates to novel pyrrolidine derivatives of formula (I), wherein R1, R2 and R3 are as defined herein, as inhibitors of glutaminyl cyclase (QC, EC 2.3.2.5). QC catalyzes the intramolecular cyclization of N-terminal glutamine residues into pyroglutamic acid (5-oxo-prolyl, pGlu*) under liberation of ammonia and the intramolecular cyclization of N-terminal glutamate residues into pyroglutamic acid under liberation of water.

A visible light-induced oxidative esterification reaction of mandelic acid with alcohols has been developed for the synthesis of α-ketoesters. The reaction is characterised by transition metal-free nature, good yields, broad functional group tolerance, and ease of operation. A practical, neutral and mild synthetic approach is provided for α-ketoesters, which are important units of many bioactive compounds
