The present invention provides a new process for the preparation of optically active ethyl 3-hydroxy-3-phenylpropionate and their esters by enzymatic method. More particularly, the racemic ethyl 3-hydroxy-3-phenylpropionate is converted to optically active ethyl 3-hydroxy-3-phenylpropionate and their esters by enzymatic reaction with acylating agent. This invention may be employed for the synthesis of individual enantiomers of ethyl 3-hydroxy-3-phenylpropionate.
