标 题 :Process of preparing enriched enantiomers of glycerol carbonate and derivatives thereof for synthesis of β-blockers
发明人：OLIVERO ALAN G; CASSEL JONATHAN M; POULSEN JAMES R
权利人:COGNIS INC
摘要:Enriched enantiomers of glycerol Carbonate are produced under the influence of a hydrolytic enzyme, either by selective esterification of racemic glycerol carbonate or by selective hydrolysis of an ester of the racemate. The enriched enantiomeric product is readily converted to starting materials and intermediates useful in the synthesis of enantiomerically pure therapeutic agents, such as beta -adrenergic blockers.

标 题 :Antibacterial analogs of isocephalosporins
发明人：CONWAY TERRY T; LIM GARY M F; MENARD MARCEL
权利人:BRISTOL MYERS CO
摘要:There is described the stereoselective total synthesis of novel DELTA 2,3-1,4-morpholine-2-carboxylic acids possessing a fused beta -lactam ring in the 1,6-position and carrying a substituent cis to carbon 5 in the 7-position of the fused ring system represented by the general formula I wherein Z is halo or hydroxyl and X is acylamino. Also included in the invention are compounds of the above formula in which the carboxyl group at the 2-position is protected as by an easily cleavable ester group and salts of both the free acids and carboxyl-protected compounds. The compounds are potent antibacterial agents.

权利人:BRISTOL MYERS CO
摘要:There is described the stereoselective total synthesis of novel DELTA 2,3-1,4-morpholine-2-carboxylic acids possessing a fused beta -lactam ring in the 1,6-position and carrying a substituent cis to carbon 5 in the 7-position of the fused ring system represented by the general formula I wherein X is acylamino and Z represents optionally substituted C1-C6 alkyl, aryl or aralkyl. Also included in the invention are compounds of the above formula in which the carboxyl group at the 2-position is protected as by an easily cleavable ester group and salts of both the free acids and carboxyl-protected compounds. The compounds are potent antibacterial agents.
