## Abstract The new chiral β‐aminoalcohols of indolinylmethanols (__1__) and their reduced derivatives (__2__) were synthesized from (__S__)‐indoline‐2‐carboxylic acid. Both (__R__) and (__S__) enantiomers of the optically active secondary alcohols have been successfully obtained in high enantiomer
