标题:Novel dibasic acid salts and their synthesis

权利人:ETHYL CORP
摘要:The protecting group, Z, of protected alpha-amino acid esters of the formula n n Z--NH--CH(R.sub.2)COOCH(R)COOR.sub.1 n n is removed in the presence of a dibasic acid such as oxalic acid. This results in the formation of a new type of salt of an amino acid ester which may be represented by the formula ##STR1## In the above Q is a divalent hydrocarbyl residue of a dibasic acid, R is a hydrogen atom or hydrocarbyl group, R 1 is a hydrocarbyl group, R 2 is a hydrogen atom or hydrocarbyl group, and p is zero or one, preferably zero. When p is zero, the salts are oxalate salts. When p is one, the salts are salts of other dibasic acids. The salts (II) are useful as reactants in the synthesis of amino-acid substituted phosphazene polymers.

标 题:Process for the synthesis of o-substituted oxime compounds
发明人：CHEMPOLIL THOMAS MATHEW
权利人:ALLIED SIGNAL INC
摘要:A novel process for the production of O-substituted oximes is disclosed. The process involves reacting an oxime with an alkali-metal hydroxide optionally in a solvent which forms an azeotrope with water to form a mixture of the alkali metal salt of the oxime and water, removing all or a portion of the water by distilling the mixture azeotropically and reacting the distilled mixture with an alpha halo carboxylic acid.

发明人：DEXTRAZE PIERRE
权利人:BRISTOL MYERS CO
摘要:A novel process is disclosed for converting known 3,4-disubstituted azetidinones to carbapenems. The process proceeds through novel N-substituted intermediates and then cyclizes to the 4-position of the azetidinone to form the carbapenem.

摘要:This invention provides novel azetidinone intermediates having the formulas: ##STR1## wherein R 1 is hydrogen, or a conventional hydroxy-protecting groups; R 2 , R 4 , and R 5 are independently selected from the group consisting of hydrogen; substituted and unsubstituted: alkyl, alkenyl, and alkynyl having from 1-10 carbon atoms; cycloalkyl, cycloalkylalkyl, and alkylcycloalkyl having 3-6 carbon atoms in the cycloalkyl ring and 1-6 carbon atoms in the alkyl moieties; spirocycloalkyl having 3-6 carbon atoms; phenyl; aralkyl, aralkenyl, and aralkynyl wherein the aryl moiety is phenyl and the aliphatic portion has 1-6 carbon atoms; or various heterocyclic moieties; and R 6 is methanesulfonyl or p-toluenesulfonyl; which are useful in the preparation of carbapenem antibiotics.
