โฆ Synopsis
A new and effective method using lipase from Candida antarctica (native or Novozym SP-435) for the preparation of enantiopure primary R-amines is reported. Hydrolysis of rat-N-acetyl-amines resulted in high conversion > 40% (168 hrs) and > 48 % (> 240 hrs) and enantiomeric excesses (> 99 %ee) for both the product and the remaining substrate.

A convenient enzymatic method is presented for the preparation of optically pure 2-hydroxy-2-arylethanephosphonates. It is proved that 2-butyryloxy-2-arylethanephosphonates can be enantioselectively hydrolyzed in diisopropyl ether equilibrated with water to give both isomers in high yield and excell
