PRODUCTION OF STEREOSPECIFIC 4-(2,3- EPOXYPROPOXY)PHENYL ACETATE,4-(2-HYDROXY-3- ISOPROPYLAMINOPROPOXY)PHENYL ACETATE AND (OR) ATENOLOL |
摘要 |
<p>S-(-)-atenolol (4-(2-hydroxy-3-isopropylaminopropoxy)phenyl acetamide) is obtained by a process including the step of stereo-specific epoxidation by an ester of 4-allyloxyphenylacetic acid using a micro-organism capable of stereo-selective epoxidation, e.g. Pseudomonas oleovorans, to produce the corresponding ester of 4-(2,3-epoxypropoxy)phenylacetic acid which is predominantly in S configuration. Pseudomonas oleovorans ATCC 29347 produces at least about 90% of the epoxypropoxy compound in S configuration. The resulting epoxypropoxy compound can be converted into atenolol, maintaining the high proportion of S configuration, by reacting the epoxypropoxy compound with isopropylamine and converting the ester group to an amide group by reaction with ammonia.</p> |
