摘要:
The present invention relates to a method for the preparation of C2-symmetric 1,4-diols of the formula IVA or IVB, wherein ring A, R1 and R2 have the meanings given in the specification, that makes use of the metallation of pure enantiomers of alpha-(aryl or heteroaryl)-alpha-substituted alkanol compounds or the use of said alkanol compounds in the preparation of said mmetric 1,4-diols; novel C2-symmetric 1,4-diols in enantiomerically pure form; and methods of use or their use in the synthesis of chiral ligands which find use to produce catalysts for a variety of asymmetric transformations such as hydrogenations.
