The stereoselective synthesis of enantioenriched anti-and syn-4-aminoalk-1-yn-3-ols is described. Initial reaction of racemic 3-(methoxymethoxy)allenylzinc with enantiopure Ellman's (SS)-(tert- butylsulfinyl)imines was shown to give straightfor

Optically pure tert-butanesulfinyl aldimines 1 were prepared by direct condensation of chiral tert-butanesulfinamide 3 with aldehydes 2 in high yields in the presence of KHSO4. The main advantage of KHSO4 is that it is applicable to the condensation reactions of a variety of aldehydes, including electron deficient and electron rich (hetereo)aromatic aldehydes, as well as aliphatic aldehydes.
