Quality Control of (S)-4-Benzyl-2-(isoquinolin-1-yl)-4,5-dihydrooxazole. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: (S)-4-Benzyl-2-(isoquinolin-1-yl)-4,5-dihydrooxazole, is researched, Molecular C19H16N2O, CAS is 2058236-52-3, about Enantioselective Palladium-Catalyzed Oxidative Cascade Cyclization of Aliphatic Alkenyl Amides.

The catalyst system of Pd(TFA)2/(S,S)-diPh-pyrox is reported to promote the highly efficient enantioselective oxidative cascade cyclization of alkene-tethered aliphatic acrylamides under mild aerobic conditions. Pyrrolizidine derivatives were synthesized in good yield and excellent enantioselectivity. D-labeling experiments revealed that the reaction proceeded through an anti-aminopalladation (anti-AP) pathway with high selectivity. The transition states for the anti-AP step account for the observed enantioselectivity.
As far as I know, this compound(2058236-52-3)Quality Control of (S)-4-Benzyl-2-(isoquinolin-1-yl)-4,5-dihydrooxazole can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
