  Optically pure aromatic diols were synthesized by the highly enantioselective dialkylation of aromatic dialdehydes with dialkylzincs in the presence of a catalytic amount of chiral aminoalcohol 1 or chiral thiophosphoramide alcohol 2 with Ti(O-i-Pr)4. The chiral titanium(IV) alkoxide of 4b, a diisopropylated product of isophthalaldehyde, catalyzed the addition of diisopropylzinc to isophthalaldehyde

  在催化量的手性氨基醇1或手性硫代磷酰胺醇2与Ti（O- i- Pr）4催化下，通过芳族二醛与二烷基锌的高度对映选择性二烷基化反应合成了光学纯的芳族二醇。间苯二醛的二异丙基化产物的4b手性钛（IV）醇盐催化将二异丙基锌加到间苯二甲醛中，通过对映选择性自感应反应（高达44％ee）得到具有相同构型的手性醇锌4b。

  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 α-(aryl or heteroaryl)-α-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.
