    Abstract

    6-Alkylsulfanyl-1,4-dihydropyridines 5 bearing methoxyphenyl groups at various positions have been prepared by three different approaches. Multidrug resistance modulating (P-glycoprotein and multidrug resistance protein-1 inhibition) activity of 1,4-dihydropyridine derivatives 5 is comparable to that of verapamil.

  • A facile synthesis of trisubstituted alkenes from β-diketones and aldehydes with AlCl3 as catalyst

    Preparation of trisubstituted alkenes from low-activity β-diketones and aldehydes with aluminum chloride as catalyst has been studied. The frequently used catalyst AlCl3 is used for the first time to promote this condensation. The procedure is a convenient, low toxicity, and highly efficient method for industrial synthesis of trisubstituted alkenes in high yield.

  • Rates of reaction of <i>n</i>-butanethiol with some conjugated heteroenoid compounds
    作者:C. E. Lough、D. J. Currie、H. L. Holmes
    DOI:10.1139/v68-127
    日期:1968.3.1

    The reactions of substituted 3-benzal-2,4-pentanediones, ethyl benzalacetoacetates, diethyl benzalmalonates, benzalmalonamides, cinnamalmalononitriles, β-nitrostyrenes, and β-nitropropenylbenzenes with excess n-butanethiol go essentially to completion in 20% aqueous ethanolic solution buffered to pH 7. The second order rate constants derived from the reactions of meta- and para- substituted derivatives correlate well with Hammett a constants. The nature and conformation of the functional group cis to the phenyl group determines the extent to which ortho substituents hinder the reaction.

    替代3-苯甲酮-2,4-戊二酮、乙基苯基乙酮酸酯、二乙基苯基丙二酸酯、苯基丙二酰胺、肉桂基丙烯腈、β-硝基苯乙烯和β-硝基丙烯基苯在过量正丁硫醇存在下在pH 7缓冲的20%乙醇水溶液中基本上完全反应。从间位和对位取代衍生物的反应中得出的二阶速率常数与Hammett a常数很好地相关。苯基团顺式于苯基团的功能团的性质和构象决定了邻位取代物对反应的阻碍程度。
