A chemoenzymatic manufacturing process for the preparation of high value chemicals includes the enzymatic oxidation of ethanol using an oxidizing biocatalyst to form an acetaldehyde intermediate. In addition, the process includes contacting of the acetaldehyde intermediate with a carboligating biocatalyst to form pyruvic acid. Further, the process includes reacting pyruvic acid with ethanol to form ethyl pyruvate. Still further, the process includes contacting the ethyl pyruvate with a metal catalyst and hydrogen to form ethyl lactate. The process also includes hydrolyzing the ethyl lactate to produce lactic acid. Moreover, the process includes contacting at least a portion of the lactic acid with a dehydrating catalyst to form acrylic acid. In addition, the process includes contacting at least a portion of the lactic acid with a metal catalyst and hydrogen to form propylene glycol and n-propanol.
