摘要:Abstract(#br)Zn-catalyzed asymmetric alkylation reaction with carbonyl compounds has provided a straightforward method to access enantio-enriched tertiary alcohols. This chiral carbon-carbon bond forming process has attracted great attention in the field of asymmetric synthesis w...

摘要:Abstract(#br)In this article, the design and synthesis of the chiral camphor derived γ-amino thiol ligand 17 and its application in catalytic enantioselective carbon-carbon forming reactions through the addition of organozinc reagents to carbonyl compounds is described. The ...

摘要:Abstract(#br)Vanadium catalysts bearing (+)-ketopinic acid-based chiral hydroxamic acids as constituent ligands are investigated in the asymmetric epoxidation of allylic alcohols. Chiral ligands lacking an N -substituent and those having a bulkier aryl group in the bornane skelet...

摘要:Abstract(#br)This investigation describes that in the presence of 2.5 mol % of (−)-2- exo -morpholinoisobornane-10-thiol (MITH) 1 , catalytic asymmetric alkynylation of aldehydes gives enantioenriched propargylic alcohols with good enantioselectivities.

摘要:Abstract(#br)The asymmetric addition of diethylzinc to aromatic and aliphatic aldehydes, including linear aliphatic ones, catalyzed by 2 mol % of β-amino alcohol (1 S , 2 R )-7,7-dimethyl-1-morpholin-4-yl-bicyclo[2.2.1]heptan-2-ol 10 gave the corresponding secondary alcohols...
