A facile three-step synthesis of 1,2-amino alcohols using the Ellman homochiral tert-butylsulfinamide
摘要:
Addition of organometallic reagents to tert-butylsulfinimines derived from tert-butyldimethylsiloxyacetaldehyde stereoselectively generates protected 1,2-amino alcohols. Removal of the acid labile protecting groups affords amino alcohols in high yield. The predominant diastereomer is opposite to that predicted by the traditional Ellman model; therefore, a chelation model invoking rapid E/Z isomerization of the imine is proposed to rationalize the observed selectivity.

An efficient methodology for the synthesis of sphingoid-type bases is reported. It involves the stereoselective addition of a racemic 3-alkoxy allenylzinc to enantiopure N-tert-butylsulfinyl imines and a cross-metathesis reaction as the key steps. It has been successfully applied to the syntheses of sphinganine and naturally occurring bioactive related compounds, among which the hydrolysis product
