  • Halogenation of β-Alkoxyvinyl Polyhaloalkyl Ketones: A Convenient Route for the Synthesis of α-Chloro- or α-Bromo-β-alkoxyvinyl Polyhaloalkyl Ketones
    作者:Igor I. Gerus、Liliya M. Kacharova、Sergei I. Vdovenko
    DOI:10.1055/s-2001-11435
    日期:——
    A number of α-chloro- and α-bromo-β-alkoxyvinyl polyhaloalkyl ketones 4 and 5 were synthesized in high yields by halogenation of β-alkoxyvinyl polyhaloalkyl ketones 1 with chlorine or bromine and further dehydrohalogenation of dihalo-intermediates 2 and 3 with pyridine. The Z configuration of ketones 4 and 5 was deduced from X-ray analysis and NMR spectra. Some typical nucleophilic reactions of the title compounds 4 and 5 with amines were carried out to check their reactivity.
    通过对δ-烷氧基乙烯基多卤烷基酮 1 进行卤化,并进一步用吡啶对二氢中间体 2 和 3 进行脱氢卤化,高产率地合成了一些δ-和δ-烷氧基乙烯基多卤烷基酮 4 和 5。根据 X 射线分析和核磁共振光谱推断出了酮 4 和酮 5 的 Z 构型。标题化合物 4 和 5 与胺进行了一些典型的亲核反应,以检验它们的反应活性。
  • β-Ethoxyvinyl polyfluoroalkyl ketones — versatile synthones in fluoroorganic chemistry
    作者:I.I. Gerus、M.G. Gorbunova、V.P. Kukhar
    DOI:10.1016/0022-1139(94)03130-4
    日期:1994.12
    material for the synthesis of various fluoro-containing compounds such as heterocycles, enones, enaminones and chelate complexes. The 4,4,4-trifluoro-3-oxo-l-butenyl group formed by β-ethoxyvinyl trifluoromethyl ketone is a suitable protecting group for the N-H terminal of amino acids in peptide synthesis. The formation of peptides using these protected amino acids occurs without racemization.
    我们已经发现,容易获得的β-乙氧基乙烯基甲基酮是合成各种含化合物(例如杂环,烯酮,烯胺酮和螯合物)的方便和全面的起始原料。由β-乙氧基乙烯基甲基酮形成的4,4,4-三-3-氧-1-丁烯基是肽合成中氨基酸NH末端的合适保护基。使用这些受保护的氨基酸形成肽时不会发生外消旋作用。
  • Regioselective Addition of Trimethylsilyl Cyanide to β-Alkoxyvinyl Alkyl Ketones
    作者:Igor S. Kruchok、Igor I. Gerus、Valery P. Kukhar
    DOI:10.1016/s0040-4020(00)00603-7
    日期:2000.8
    The 1,2- and 1,4-addition reactions of trimethylsilyl cyanide to alkyl vinyl ketones were studied. Regioselectivity of this reaction depends on the structure of alkyl vinyl ketones, the reaction temperature and the nature of catalyst. The presence of alkoxy group in beta-position of alpha,beta-enone is the important condition for realization of 1,4-addition. Ambient temperature (25 degrees C) or base catalyst (NEt3) directed the reaction predominantly into 1,2-addition; higher temperature, electrophilic catalyst (I-2) and bulky alkyl substituents near the carbonyl group directed the reaction in 1,4-addition route. Hydrolysis of 1,4-adducts yields saturated fluorine-containing ketones containing CN- and ethoxy groups at the beta-position. (C) 2000 Published by Elsevier Science Ltd.
