Stable aminoalcohol formation with glycine. a Aldehyde with H-bond acceptors forms a stable aminoalcohol with 1a (also see Supplementary Fig. 72). b Selective formation of aminoalcohol with 1a. c Stereo-stability of substituted amino acid (1n) under the reaction conditions. d Plausible mechanism for glycine specific formation of aminoalcohol
