Kinetic resolution of racemic epoxides using a chiral diamine catalyst
摘要:
The kinetic resolution of a variety of racemic epoxides has been performed using a chiral bicyclic diamine ligand. Using 5 mol% of catalyst very high selectivity could be achieved; both epoxide and the corresponding allylic alcohol could be obtained in up to 99% ee. (c) 2005 Elsevier Ltd. All rights reserved.

[formula: see text] The kineticresolution of racemic epoxides via catalytic enantioselective rearrangement to allylicalcohols was investigated. Using the Li-salt of (1S,3R,4R)-3-(pyrrolidinyl)methyl-2-azabicyclo [2.2.1] heptane 1 as catalyst allowed both epoxides and allylicalcohols to be obtained in an enantioenriched form.
