标 题 :Synthesis of d-2-amino-1-butanol
发明人：SINGH BALWANT
权利人:AMERICAN CYANAMID CO
摘要:D-2-Amino-1-butanol, for the synthesis of ethambutol hydrochloride, d,d'-2,2'-(ethylenediimino)di-1-butanol dihydrochloride, is produced in high purity and good yields by the reaction of butene-1, a nitrile, preferably an excess of acetonitrile, and chlorine to form N-[1-(chloromethyl)propyl]acetimidoyl chloride which is hydrolyzed to dl-2-amino-1-butanol, which can be isolated as the hydrochloride, or free base, or a mixture, resolved with L(+)- tartaric acid and the d-2-amino-1-butanol reacted with ethylene dichloride and then hydrochloric acid to form ethambutol hydrochloride. A minimum of by-products which are conveniently split out permits the economical synthesis of a pharmaceutical grade product.

标 题 :Enantiomeric enrichment and stereoselective synthesis of chiral amines
发明人：STIRLING DAVID I; MATCHAM GEORGE W; ZEITLIN ANDREW L
权利人:CELGENE CORP
摘要:Amines in which the amino group is on a secondary carbon atom which is chirally substituted can be enantiomerically enriched by the action of an omega-amino acid transaminase which has the property of preferentially converting one of the two chiral forms to a ketone. The process also can be used to stereoselectively synthesize one chiral form from ketones substantially to the exclusion of the other.

摘要:Amines in which the amino group is on a secondary carbon atom which is chirally substituted can be enantiomerically enriched by the action of an omega-amino acid transaminase which has the property of preferentially converting one of the two chiral forms to a ketone. The process can be used to stereoselectively sythesize one chiral form from ketones substantially to the exclusion of the other. An aqueous solution of chiral amines after being brought into contact with an omega-amino acid transaminase and an amino acceptor is treated with a water-immiscible organic solvent, the aqueous and organic phases are separated, and the aqueous phase can be recirculated for further contact with the transaminase.
