DIRECT ENANTIOSELECTIVE SYNTHESIS OF SYN-1,3-DIOLS BY THE REACTION OFALDEHYDES WITH ENOL SILYL ETHERS IN THE PRESENCE OF A CHIRAL BORANE COMPLEX - SUCCESSIVE ASYMMETRIC ALDOL REACTION AND ASYMMETRIC REDUCTIONWITH ONE PROMOTER
Y. Kaneko et al., DIRECT ENANTIOSELECTIVE SYNTHESIS OF SYN-1,3-DIOLS BY THE REACTION OFALDEHYDES WITH ENOL SILYL ETHERS IN THE PRESENCE OF A CHIRAL BORANE COMPLEX - SUCCESSIVE ASYMMETRIC ALDOL REACTION AND ASYMMETRIC REDUCTIONWITH ONE PROMOTER, Tetrahedron letters, 35(24), 1994, pp. 4107-4110
A stoichiometric amount of the chiral borane 1 turned out to successiv
ely promote the asymmetric aldol reaction of aldehydes with enol silyl
ethers and the following asymmetric reduction in one pot to afford sy
n-1,3-diols with high enantioselectivity.
