M. Falorni et al., CHIRAL LIGANDS CONTAINING HETEROATOMS .14. 1,3-OXAZOLIDINYL METHANOLSAS CHIRAL CATALYSTS IN THE ENANTIOSELECTIVE ADDITION OF DIETHYLZINC TO ALDEHYDES, Tetrahedron : asymmetry, 7(1), 1996, pp. 293-299
Starting from L-serine and L-threonine, phenyl-(2,2-dimethyl-1,3-oxazo
lidin-4-yl)-methanol and ,2-dimethyl-5-methyl-1,3-oxazolidin-4-yl)-met
hanol were prepared in good yields. The use of these compounds as very
efficient chiral catalysts for the enantioselective addition of dieth
ylzinc to aldehydes is described. This paper reports the first example
of the use of oxazolidine methanols in asymmetric synthesis.
