Short and Simple Synthesis of (r)

Both (R)- and (S)-4-hydroxypentylaminoacetamide have been synthesized by reductive amination of glycinamide on the gamma-valerolactols corresponding to (R)- and (S)-gamma-valerolactone respectively These enantiomeric lactones were readily obtained in high enantiomeric excess (ee) by enzymic porcine pancreatic lipase (PPL) kinetic resolution
