Chiral scandium-catalysed enantioselective ring-opening of meso-epoxides with N-heterocycle, alcohol and thiol derivatives in water

In the presence of catalytic amounts of Sc(OSO3C 12H25)3 and a chiral bipyridine ligand, asymmetric ring-opening of meso-epoxides with aromatic N-heterocycles, an alcohol and thiols proceeded smoothly to afford

Lithium BINOL phosphate catalyzed desymmetrization of meso-epoxides with aromatic thiols

A highly enantioselective method for desymmetrization of meso-epoxides using thiols is reported. This is the first example of epoxide activation achieved using metal BINOL phosphates. The reaction has a broad scope in terms of epoxide substrates and aroma

Catalytic asymmetric ring-opening reaction of meso-epoxides with aryl selenols and thiols catalyzed by a heterobimetallic gallium-titanium-salen complex

A chiral heterobimetallic Lewis acid complex has been developed as an efficient catalyst. The enantioselective desymmetrization of meso-epoxides with aryl selenols and thiols catalyzed by the heterobimetallic complex has been optimized. The optically active β-arylseleno alcohols and β-hydroxy sulfides were obtained in good yields and high enantioselec- tivities (up to 97% ee and 92% ee, respectively). A strong synergistic effect between different Lewis acids was exhibited in the catalytic process. & copy; 2009 Wiley-VCH Verlag GmbH & Co. KGaA.

Enantioselective synthesis of a novel chiral 2,9-disubstituted 1,10-phenanthroline and first applications in asymmetric catalysis

The asymmetric synthesis of a novel, C2-symmetric, tetradentate 1,10-phenanthroline is described; it is based on the stereoselective preparation of two functionalized pyridine subunits, which were subsequently joined through two consecutive car

Salan-vanadium catalyzed enantioselective desymmetrization of meso-epoxides with aromatic thiols

The first example of salan-vanadium catalyzed enantioselective ring-opening of meso-epoxides has been reported, which furnished β-hydroxy sulfides in good yields and moderate enantioselectivities.

Enantioselective ring-opening reaction of meso-epoxides with ArSH catalyzed by heterobimetallic Ti-Ga-Salen system

The enantioselective ring-opening reaction of meso-epoxides with aryl thiols catalyzed by a chiral heterobimetallic Ti-Ga-Salen complex was realized, and the 1,2-mercapto alcohols were obtained in good yields and moderate to high enantioselectivities (up

Indium-bipyridine-catalyzed, enantioselective thiolysis of meso-epoxides

The indium-bipyridine-catalyzed, enantioselective ring-opening of meso-epoxides with aliphatic and aromatic thiols furnished 1,2-mercapto alcohols in good yields and excellent enantioselectivities; the crystal structure of the chiral catalyst reveals a pe

Chiral scandium-catalyzed highly stereoselective ring-opening of meso-epoxides with thiols

The desymmetrization of meso-epoxides with thiols proceeded smoothly in dichloromethane or dichloroethane in the presence of a catalytic amount of a chiral scandium complex consisting of Sc(OTf)3 and chiral bipyridine 1, to afford the correspon

Enantioselective ring-opening reaction of meso-epoxides with ArSH catalyzed by a C2-symmetric chiral bipyridyldiol-titanium complex

This study describes a C2-symmetric ligand comprising a central bipyridine-pinene-derived core and two functionalized diphenylmethanol subunits. [8′-(Hydroxy-diphenyl-methyl)-10,10,10′,10′-tetramethy l-[5,5′]bi[6-aza-tricyclo[7.1.1.02,7/s
