  • Methylation or ethylation agent and process for 1,4-addition of a methyl
    申请人:Schering Aktiengesellschaft
    公开号:US05908944A1
    公开(公告)日:1999-06-01
    This invention describes a new methylation or ethylation agent containing trimethyl aluminum or dimethyl zinc or triethyl aluminum as methyl or ethyl source, which additionally contains catalytic amounts of one or more copper(I) and/or copper(II) compounds as well as a process for the 1,4-addition of a methyl or ethyl group to an .alpha.,.beta.-unsaturated or an .alpha.,.beta.-double unsaturated ketone or an .alpha.,.beta.-unsaturated aldehyde using the agent according to the invention. By using only catalytic amounts of copper and a CKW (chlorinatedhydrocarbon)-free reaction medium, the new methylation/ethylation agent/process is distinguished by its environmental compatibility and it is, for example, suitable for the production of initial products for the synthesis of biologically effective compounds.

    (DE) Die vorliegende Erfinding beschreibt ein neues Methylierungs- bzw. Ethylierungsmittel, enthaltend Trimethyaluminium oder Dimethylzink bzw. Triethylaluminium als Methyl- bzw. Ethylquelle, welches zusätzlich katalytische Mengen einer oder mehrerer Kupfer-I- und/oder Kupfer-II-Verbindungen enthält sowie ein Verfahren zur 1,4-Addition einer Methyl- oder Ethylgruppe an ein $g(a),$g(b)-ungesättigtes oder ein $g(a),$g(b)-doppelt ungesättigtes Keton oder an einen $g(a),$g(b)-ungesättigten Aldehyd unter Verwendung des erfindungsgemäßen Mittels. Aufgrund der Verwendung lediglich katalytischer Kupfermengen und eines CKW (Chlorkohlenwasserstoff)-freien Reaktionsmediums zeichnet sich das neue Methylierungs-/Ethylierungsmittel/Verfahren durch seine Umweltverträglichkeit aus und es ist beispielsweise zur Herstellung von Ausgangsprodukten für die Synthese biologisch wirksamer Verbindungen geeignet.(EN) A new methylating or ethylating agent, containing trimethyl aluminium or dimethyl zinc or triethyl aluminium as methyl or ethyl source, further contains catalytic amounts of one or several cuprous and/or cupric compounds. Also disclosed is a process for 1,4-adding a methyl or ethyl group to an $g(a),$g(b)-unsaturated or to an $g(a),$g(b)-bisunsaturated ketone or to an $g(a),$g(b)-unsaturated aldehyde by means of the disclosed agent. As only catalytic amounts of copper and a chlorinated hydrocarbon-free reacting agent are used, this new methylating/ethylating agent and process are characterized by being environmentally safe and are useful for example for preparing starting materials for the synthesis of biologically active compounds.(FR) La présente invention concerne un nouvel agent de méthylation ou d'éthylation, contenant du triméthylaluminium ou du diméthylzinc ou bien du triéthylaluminium comme source de méthyle ou d'éthyle, et également des quantités catalytiques d'un ou de plusieurs composés cuivreux et/ou cuivriques. L'invention concerne également un procédé d'addition en position 1 et 4 d'un groupe méthyle ou éthyle à une cétone $g(a),$g(b) insaturée, ou $g(a),$g(b) biinsaturée ou bien à un aldéhyde $g(a),$g(b) insaturé au moyen dudit agent de méthylation ou d'éthylation. Etant donné que pour réaliser ce nouveau procédé de méthylation ou d'éthylation on utilise simplement des quantités catalytiques de cuivre et d'un milieu de réaction exempt d'hydrocarbures chlorés, ledit agent et le procédé se caractérisent par leur compatibilité avec l'environnement et conviennent, par exemple, à la préparation de produits de départ pour la synthèse de composés biologiquement actifs.

  • Neurosteroid Analogues. 4. The Effect of Methyl Substitution at the C-5 and C-10 Positions of Neurosteroids on Electrophysiological Activity at GABA<sub>A</sub> Receptors
    作者:Mingcheng Han、Charles F. Zorumski、Douglas F. Covey
    DOI:10.1021/jm960304p
    日期:1996.1.1
    A series of analogues of the neuroactive steroids 3 alpha-hydroxy-5 alpha-pregnan-20-one and 3 alpha-hydroxy-5 beta-pregnan-20-one were studied to elucidate the mode of binding of 5 alpha- and 5 beta-reduced steroids to steroid binding sites on GABA(A) receptors. Analogues which were either 3 alpha-hydroxy-20-ketosteroids or 3 alpha-hydroxysteroid-17 beta-carbonitriles and which contained various methyl group substitution patterns at C-5 and C-10 were prepared. Evaluations utilized whole-cell patch clamp electrophysiological methods carried out on cultured rat hippocampal neurons, and the results obtained with the rigid 17 beta-carbonitrile analogs were analyzed using molecular modeling methods. The molecular modeling results provide a rationale for the observation that the configuration of the hydroxyl group at C-3 is a greater determinant of anesthetic potency than the configuration of the A,B ring fusion at C-5. The electrophysiological results identify steric restrictions for the space that can be occupied in 5 alpha- and 5 beta-reduced steriod modulators of GABA(A) receptors in the regions of space proximate to the steroid C-5, C-10, and possibly C-4 positions. This information is useful for the development of nonsteroidal analogues that can modulate GABA(A) receptors via interactions at steroid binding sites.
  • Analogues of androgen hormones with inverted configuration at carbons 5, 9, and 10
    作者:Alexander Kasal、Milos̆ Budĕs̆ı́nský、Pavel Dras̆ar
    DOI:10.1016/s0039-128x(01)00135-0
    日期:2002.1
    On catalytic hydrogenation of Delta (9)-steroids (e.g. 3 beta -hydroxy-5-methyl-19-nor-5 beta -androst-9-en-17-one), four isomers were formed: 9 alpha ,10 alpha-, 9 alpha ,10 beta-, 9 beta ,10 alpha- and 9 beta ,10 beta -adducts. The product distribution was affected by the nature of the C-3 substituent. A chair conformation of A, B, and C rings was found in all of the products with the exception of the 9 alpha ,10 alpha -adduct whose B ring adopts a twist boat conformation. The products were utilized for the synthesis of dihydrotestosterone analogues. (C) 2002 Elsevier Science Inc. All rights reserved.
