ENZYMATIC RESOLUTION OF AN ARYLPIPERIDINE DERIVATIVE UTILIZING LIPASE CATALYZED HYDROLYSIS
Nieduzak, Thaddeus R.,Carr, Albert A.
, p. 535 - 536 (1990)
Enantiospecific hydrolysis of the acetate 1 was carried out on a multigram scale utilizing a lipase from Aspergillus niger.Both stereoisomers R-(+) and S-(-) were obtained with high enantiomeric purity (>97 percent ee).
