摘要:
A novel process for the preparation of 6-aminopenicilanic acid-1,1-dioxide and its non-toxic, pharmaceutically acceptable salts by deacylation of a penicillin-1,1-dioxide or its salts of which the 3-carboxylic acid is protected by such an easily removable group that a "one-pot process" is possible.

6-Alpha and 6-beta-substituted penicillanic acid derivatives of the formula: ##STR1## wherein R is H or a conventional penicillin carboxy protecting group or an ester forming residue readily hydrolyzable in vivo and R.sup.1 is a perhaloalkyl group of from 1 to 4 carbon atoms wherein the halogen atoms are fluoro or chloro, undergo SN.sub.2 nucleophilic displacement with halide or azide ions with inversion of configuration at C-6 to yield the corresponding 6-beta or 6-alpha-halo- or azido-substituted product.
摘要:
4,4',7,7'-Tetrachlorothioindigo can be obtained in a form directly suitable for use as a pigment if the oxidation of 3-hydroxy-4,7-dichloro-1-thionaphthene is performed in an alkaline medium in the presence of oxygen or an oxygen-containing gas.
摘要:
A process is provided which yields derivatives of cephalosporins and penicillins. The process starts with 7-acylaminocephalosporin, or 6-acylaminopenicillin, then the latter compounds are treated with an organolithium compound, followed with t-butyl-hypochlorite. Finally, a defined reagent is added yielding a side chain on the carbon adjacent to the amino-nitrogen. Novel intermediate compounds are also described. The end compounds prepared are active against both gram-positive and gram-negative bacteria.
摘要:
6-[.alpha.-(Imidazolidin-2-on-1-carbonylamido)acetamido]-penicillanic acids substituted in the 3-position of the imidazolidinone ring with phenyl or a substituted phenyl group and on the .alpha.-carbon atom of the acetamido bridge with a phenyl, thienyl, cyclohexenyl or cyclohexadienyl group, and their salts, are antibacterial agents. The compounds, of which .alpha.-(3-phenylimidazolidin-2-on-1-ylcarbonylamino)benzylpenicillin is a representative example, are prepared by acylation of the corresponding 6-(.alpha.-aminoacetamido)penicillanic acid or a derivative thereof.
