Asymmetric reduction of ketones by using complexes of lithium tetrahydridoaluminate(III) with 1,4:3,6-dianhydro-D-mannitol and 1,3:4,6-di-O-benzylidene-D-mannitol
Abstract
The use of chiral diols each containing a two-fold axis of symmetry to achieve asymmetric reductions of some ketones with metal hydrides is described. The symmetry of these complexes simplifies interpretation of the observed enantioselectivity.
