  Cobalt-Catalyzed Enantioselective Intramolecular Hydroacylation of Ketones and Olefins

  摘要：

  Cobalt-chiral diphoshine catalytic systems promote intramolecular hydroacylation reactions of 2-acylbenzaldehydes and 2-alkenylbenzaldehydes to afford phthalide and indanone derivatives, respectively, in moderate to good yields with high enantioselectivities. The ketone hydroacylation did not exhibit a significant H/D kinetic isotope effect (KIE) with respect to the aldehyde C-H bond, indicating that C-H activation would not be involved in the rate-limiting step.

  A nickel-catalyzed asymmetric Suzuki–Miyaura cross-coupling of racemic 3-bromo-phthalides and arylboronic acids was realized for the synthesis of diverse chiral 3-aryl-phthalides in moderate to excellent reaction yields. The reaction proceeded in a stereoconvergent manner and high enantioselectivities were observed for most examined examples. A number of functional groups like aldehyde, ester and bromide

  Binaphthyl–prolinol ligands were designed and applied in enantioselective arylation of aromatic aldehydes and sequential arylation–lactonization of methyl 2-formylbenzoate. Under optimized conditions, the reactions provided the desired diarylmethanols and 3-aryl phthalides in up to 96% yields with up to 99% ee and up to 89% yields with up to 99% ee, respectively. In particular, essentially optically

  日期：2020.5.1

  An asymmetric rhodium(III)-catalyzed Grignard-type addition of inert arene C-H bond to aldehydes is reported. It provides a new strategy for the synthesis of chiral 3-substituted phthalides in good yields (up to 87%) with high enantiomeric purity (up to 99% ee). Interestingly, a chiral-matching effect between substrate and catalyst was observed, which is crucial to accomplish satisfied reaction outcomes

  DOI：10.1039/c8ob02872a

  日期：——

  The catalytic asymmetric synthesis of 3-aryl phthalides is reported through a sequential asymmetric arylation–lactonization reaction. The reaction is enabled by a boron–zinc exchange to generate reactive arylating agents, which react with 2-formylbenzoates in the presence of a chiral amino naphthol ligand. The enantiodetermining step is the arylation of the aldehyde, which then undergoes a lactonization
