Enzymatic resolution of N-acetyl-homophenylalanine with mammalian kidney acetone powders

Add time:07/18/2019    Source:sciencedirect.com

Kidney acetone powders (KAP) from beef, dog, hog, rat, and sheep have been evaluated for resolving N-acetyl-dl-homophenylalanine. We also propose a simple protocol for the preparation of both enantiomers of homophenylalanine by enzymatic resolution using mammalian KAP. The beef kidney afforded the best results, rendering the highest isolated yields, 37.5% and 41% and enantiomeric excesses of 94% and >99% for both d-N-Ac-homophenylalanine and l-homophenylalanine, respectively.
