Optically active N-1-phenylethyl derivatives of (1R)-2-amino-1-phenylethanol as chiral auxiliaries in the enantioselective addition of diethylzinc to arylaldehydes
摘要:
The aminoalcohols (1R)-2-N[(R)-1-phenylethyl]amino-1-phenylethanol, (1R)-2-N[(S)-1- phenylethyl]amino-1-phenylethanol, and (1R)-2-N-methyl-N[(R)-1-phenylethyl]amino synthesized by simple procedures, have been used as chiral catalysts in the enantioselective addition of diethylzinc to arylaldehydes, obtaining optically active 1-arylpropanols in good chemical yields (47 to 95%) and e.e.s up to 88%.
