Zhang, Bowen published the artcileC-H Functionalization Approach for the Synthesis of Chiral C2-Symmetric 1,5-Cyclooctadiene Ligands, Safety of 4-Methoxyphenylacetic acid, the main research area is chiral cyclooctadiene stereoselective preparation; diazo cyclooctadiene rhodium catalyst ligand diastereoselective enantioselective allylic insertion.
Chiral cyclooctadiene (COD) derivatives are readily prepared by rhodium-catalyzed allylic C-H functionalization of COD.Either mono or difunctionalization of COD is possible generating the products in high yield, diastereoselectivity and enantioselectivity. The double C-H functionalization generates C2 sym. COD derivatives with four new stereogenic centers in >99% ee, which can be readily converted to a series of chiral COD ligands. Preliminary evaluations revealed that the COD ligands can be used in rhodium-catalyzed asym. arylation of cyclohex-2-enone, leading to the conjugate addition products in up to 76% ee.
Organic Letters published new progress about Arylation. 104-01-8 belongs to class isoquinoline, name is 4-Methoxyphenylacetic acid, and the molecular formula is C9H10O3, Safety of 4-Methoxyphenylacetic acid.
