    摘要: 6,6-Difluoro-11 Alpha ,16 Alpha ,17 Alpha -trihydroxy-4-pregnen3,20-dione 16,17-ketal 17-ketal is prepared by a process involving the 11 Alpha -microbiological hydroxylation of the corresponding 16 Alpha ,17 Alpha -dihydroxy steroid. The 11 Alpha -hydroxyl is converted sequentially to the 9,11-double bond, 9,11-epoxy and 9 Alpha -fluoro-11 Beta -hydroxyl. Optionally the 1,2-position is dehydrogenated and a 21-hydrogen converted to a 21-hydroxy, acyloxy, bromine or chlorine. The latter steroid ketals are highly active anti-inflammatory and glucocortical agents.

    摘要: A process is disclosed for the preparation of a 7 Beta -(4carboxybutanamide) ceph-3-3em-4-carboxylic acid or a 7 Beta -(5carboxy-5-oxopentamido) ceph-3-em-4-carboxylic acid by subjecting a 7 Beta -(D-5-amino-5-carboxypentamido) ceph-2-em-4-carboxylic acid to the action of a cell-free fungal D-amino acid oxidase. The modified cephalosporin compounds produced exhibit antimicrobial activity and are useful as presursors in the synthesis of 7-aminocephalosporanic acid and 7 Beta -acylamido analogues of cephalosporin C.

    摘要: A process for producing fatty acid esters of sugars by fermentation which comprises culturing a hydrocarbon-assimilating micro-organism under aerobic conditions in an aqueous nutrient medium containing hydrocarbons as the main source of carbon. Good yields are obtained using n-paraffins of six to 25 carbon atoms or kerosene as the hydrocarbon in the medium. Exemplary microorganisms are those belonging to the genus Arthrobacter, Brevibacterium, Micrococcus, Corynebacterium, Mycobacterium, Candida, or Aspergillus.
