Aryldiazoacetates can undergo photolysis under blue light irradiation (460–490 nm) at room temperature and under air in the presence of numerous trapping agents, such as styrene, carboxylic acids, amines, alkanes and arenes, thus providing a straighforward and general platform for their mild functionalization.
Novel, chiral Lewisbase organocatalysts, which displayed poor enantioselection in the hydrosilylation of N-aryl β-enamino esters, were found to be the catalysts of choice in the hydrosilylation of α-imino esters. In the presence of 10 mol-% of the best catalyst, various α-imino esters underwent enantioselectivehydrosilylation to provide a wide range of chiral α-amino esters with good yields (up to
