标题:Intermediates useful in camptothecin synthesis
发明人：FORTUNAK JOSEPH
权利人:SMITHKLINE BEECHAM CORP
摘要:The present invention provides a process for the asymmetric synthesis of camptothecin analogues as well as novel chemical intermediates of Formula I, II, and III. In general, the present process comprises conversion of a cis dioxolanone, having the same desired absolute configuration as the desired camptothecin analogue, to a compound of Formula I, II, or III, which compound is then converted to the desired camptothecin analogue. ##STR1##

标 题:Azo compounds and their use as dyes, 1-sulpho-6-carboxyl-amino naphthaline, its use as a diazo component and process for the production of these compounds
发明人：SPRINGER HARTMUT; HUSSONG KURT
权利人:HOECHST AG
摘要:The description relates to azo compounds corresponding to formula (1) below, having fibre-reactive properties and making valuable dyes. They can dye hydroxy and/or carbonamide group-containing synthetic and natural materials, especially fibre materials, like wool and especially cellulose fibre materials in bright colours. Formula (1) in which: M is hydrogen or a salt-forming metal like an alkaline metal; K is a residue of general formulae (2A) or (2B) in which: E is the residue of an intermediate component common in disazo dyes which can act as a coupling and as a diazo component, e.g. the residue of a 1-(aminophenyl) or -amino-naphthyl) pyrazolon, aminonaphthol, anilin or 1-amino naphthalin compound; v is the figure zero or 1; K is the residue of a water-soluble coupling component, preferably from the naphthol, aminonaphthol, anilin, pyrazolon, hydroxypyridon and acetoacetyl arylide series, whereby this coupling component contains 1 or 2 fibre-reactive groups of the vinyl sulphonate series; D is a benzol or naphthalin residue, whereby its substituents R?1 and R?2 are common ones in azo dyes, e.g. (besides hydrogen) lower alkyl, lower alkoxy, halogen, sulpho and carboxyl; the group -SO2?-Y is a fibre-reactive group of the vinyl sulphone series; a is the figure zero, 1 or 2; and k is the number 1 or 2. A description is also given of the compound 2-amino naphthaline-1-sulphonic acid-6-carboxylic acid which may be used as a pre-product in the production of dyes, e.g. as diazo component in the synthesis of dyes of general formula (1).

标题 :Production of ethylene glycol from synthesis gas
发明人：WHYMAN ROBIN
权利人:ICI LTD
摘要:A process for the production of ethylene glycol, methanol, ethanol and/or esters thereof from mixtures of carbon monoxide and hydrogen (synthesis gas) which comprises contacting a mixture of carbon monoxide and hydrogen with a catalyst at elevated pressure in a liquid medium, said catalyst comprising ruthenium and at least one other metal from Group VIII of the Periodic Table, and wherein the molar proportion of ruthenium is at least 50 percent relative to the other Group VIII metals. The process is particularly applicable to the selective production of ethylene glycol. The preferred catalysts, which comprise ruthenium/rhodium, may be present in elemental form, as coordination compounds or salts, e.g. carbonyls, acetyl acetonates or carboxylates. It is especially preferred to use a co-catalyst comprising a compound of one or more the metals of Groups IA, IIA or IIB or a nitrogen containing cation and/or base. Suitable liquid media include carboxylic acids (e.g. acetic acid) and ethers (e.g. tetraglyme).
