    名称:
    Synthesis and cytotoxic evaluation of some styryl ketones and related compounds
    摘要:
    A number of 1-aryl-4-methyl-1-penten-3-ones 1 were converted to the corresponding Mannich bases 2 and analogues 3. Attempts to form the azines 4 from several members in series 1 led to the isolation of the corresponding pyrazolines 5 or aryl aldehyde azines 6. Replacement of the isopropyl group of a compound in series 1 by methyl and ethyl functions led to ketones that reacted with hydrazine producing the corresponding azines. The Mannich bases displayed greater activity than the precursor ketones towards murine P388 and L1210 leukemia cells as well as to a panel of human tumour cell lines. Certain of the Mannich bases had selective toxicity towards some human tumour cell lines and others to L1210 cells (in contrast to human T lymphocytes). Several drug-resistant cell lines were shown to be free from cross resistance to a number of the Mannich bases.

  • Zur Darstellung von 5-Aryl-2-cyclohexenonen

    Durch basekatalysierte Reaktion zwischen aromatischen Aldehyden und 3‐Methyl‐2‐butanon in wäßrig‐ethanolischer Lösung bei 70° konnten die 5‐Aryl‐3‐isopropyl‐6,6‐dimethyl‐2‐cyclohexenone 4a‐f dargestellt werden. Benzaldehyd und Butanon reagierten analog; zwei der vier möglichen, in schlechter Ausbeute anfallenden 5‐Aryl‐2‐cyclohexenone 6 waren als Oxime zu isolieren.

  • Synthesis of Cyclopropenes and Fluorinated Cyclopropanes via Michael Initiated Ring Closure of Alkyl Triflones
    作者:Hui Wang、Ren‐Yin Yang、Bo Xu
    DOI:10.1002/chem.202104364
    日期:2022.4.22
    Various cyclopropenes and fluorinated cyclopropanes were prepared from readily available alkyl triflones and electron-deficient alkenes via a Michael addition initiated ring closure (MIRC) process. This protocol not only has a broad substrates scope but also achieves good chemical yields and moderate diastereoselectivity. The mechanism may involve tandem Michael addition of triflones/intramolecular

  • A short route to multiply substituted fluorenones
    作者:Zhanru Yu、Dolores Velasco
    DOI:10.1016/s0040-4039(99)00370-6
    日期:1999.4
    We report a two-step synthesis of polysubstituted fluorenones by condensation of malononitrile with aromatic aldehydes and methylketones or with β-aryl-α,β-unsaturated carbonyl compounds, aldehydes or ketones. The yields of the fluorenone systems depend on the nature of the substitution on the aromatic rings.

    日期:——
    (±)-Veadeiroic acid 1 and (±)-veadeirol 2, two new cleistanthoid diterpenes, have been synthesized by stereoselective cyclisation of the carbocation 5 generated from the cyclohexanol 26. The latter is prepared from 2-ethyl-3-formylbenzoic acid (with CO2H masked as an oxazoline ring) by successive reaction with 3-methylbutan-2-one, Robinson annutation, and reduction of the styrylcyclohexenone 24. The
