  Disclosed herein is a process for the manufacture of (R)-phenylacetylcarbinol ((R)-PAC), (1R,2S). Ephedrine and its salts, (1R,2S)-norephedrine and its salts and 1-(Phenyl/Substituted phenyl)-2-(amino/alkylamino/dialklyamino) propan-1-ol and its salts, by enzymatic reduction of α-isonitrosopropiophenone (INP) and substituted α-isonitrosopropiophenone (substituted INP). The β-amino alcohols, produced by the process of present invention gives their corresponding diastereomers on Walden inversion. The present preparation process of (R)-PAC with (R)-PAC oxime as an intermediate has the advantage, that propiophenone as a key raw material which is easily available and has a low-price, operationally simple with high yield and a single process leading to the synthesis of several 1,2-aminoalcohol/ β- aminoalcohols active pharmaceutical ingredients. The design approach of the process is to reduce environmental impact of the product by comparing to the present manufacturing process.
