Zhou, Likai published the artcileEnantioselective Transfer Hydrogenation of Oxocarbenium Ions Enables Asymmetric Access to α-Substituted 1,3-Dihydroisobenzofurans, Recommanded Product: 2-Bromo-4-methoxybenzoic acid, the main research area is dihydroisobenzofuran preparation enantioselective; cyclic oxocarbenium ion ketal transfer hydrogenation.
Reported here is an efficient enantioselective transfer hydrogenation of cyclic oxocarbenium ions generated in situ through collapse of the corresponding acetal substrates. The asym. approach provides straightforward access to a variety of chiral α-aryl substituted 1,3-dihydroisobenzofurans in high yields with excellent enantioselectivities. α-Alkynyl substituted 1,3-dihydroisobenzofurans were also proved to be suitable substrates. In addition, when the reaction was performed at gram scale, the desired product was obtained in good yields with excellent enantioselectivity.
Synthesis published new progress about Carbocations, carbenium. 74317-85-4 belongs to class bromides-buliding-blocks, name is 2-Bromo-4-methoxybenzoic acid, and the molecular formula is C8H7BrO3, Recommanded Product: 2-Bromo-4-methoxybenzoic acid.
