✦ Synopsis


Lipase-catalyzed amidation of 2-(2-aminoethyl)-1,1%-binaphthyl (±)-3 gave optically active 2-[2-(acylamino)ethyl]-1,1%binaphthyls (R)-6a-c with high enantiomeric excess.

Acenaphthenyl acetate and acenaphthenol are resolved through Pseudomonas fluorescens lipase (PFL)-catalyzed hydrolysis and acylation, respectively. By contrast, the structurally related 1-(1-naphthyl)ethyl acetate and 1-(1naphthyl)ethanol are inactive under the same reaction conditions.

The enzymatic dynamic kinetic resolution of N-acylhemiaminals by various lipases, namely, lipase PS, lipase AK and lipase QL, has been investigated. The acetylation of racemic N-acylhemiaminals with lipases exclusively produced the (R)-enantiomers in enantiomerically pure form and quantitative yield
