The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Enantioselective Allylic Alkylation with 4-Alkyl-1,4-dihydro-pyridines Enabled by Photoredox/Palladium Cocatalysis》.

Through the article, more information about this compound (cas:676525-77-2) is conveyed.
Highly regio- and enantioselective allylic alkylation has been achieved enabled by the merger of photoredox and palladium catalysis. In this dual catalytic process, alkyl radicals generated from 4-alkyl-1,4-dihydropyridines act as the coupling partners of the π-allyl palladium complexes [e.g., irradiation of racemic allylic acetate I and 4-benzyl Hantzsch ester in presence of Ir(ppy)2(dtbbpy)PF6 photocatalyst and Pd2(dba)3/(R)-GARPHOS in MeCN afforded II (76% GC yield, 72% isolated yield, B/L > 95:5, 94% ee)]. The generality of this method has been illustrated through the reaction of a variety of allyl esters with 4-alkyl-1,4-dihydropyridines. This mechanistically novel strategy expands the scope of the traditional Pd-catalyzed asym. allylic alkylation reaction and serves as its alternative and potential complement.
