  • Formation of 2,2-dimethylchroman-4-ones during the photoinduced rearrangement of some aryl 3-methyl-2-butenoate esters. A mechanistic insight
    作者:Daniela Iguchi、Rosa Erra-Balsells、Sergio M. Bonesi
    DOI:10.1016/j.tet.2016.02.039
    日期:2016.4
    Several aryl 3-methyl-2-butenoate esters upon irradiation lead to the formation of [1,3]-migrated photoproducts, phenol and, surprisingly 2,2-dimethylchroman-4-one derivatives. The starting photochemical reaction takes place from the singlet excited state of the ester and as a total mechanism two consecutive reaction pathways are proposed. The former involves the photo-Fries rearrangement of the esters
    辐照后的几种芳基3-甲基-2-丁烯酸酯会导致[1,3]迁移的光产物,苯酚以及令人惊讶的2,2-二甲基苯并吡喃-4-酮衍生物的形成。起始光化学反应从酯的单重激发态发生,并且作为总机理,提出了两个连续的反应途径。前者涉及酯在所有研究的溶剂中的光-弗里斯重排,并且取决于溶剂的质子性,后者涉及ESIPT过程,然后进行热6π-电环反应和/或热(分子内氧杂-迈克尔加成反应)邻位区域异构体的环化形成。该第二途径负责2,2-二甲基苯并吡喃-4-酮衍生物的形成。
  • The total synthesis of β-lapachone
    作者:Aná Claudia F. Amaral、Roderick A. Barnes
    DOI:10.1002/jhet.5570290614
    日期:1992.10
    The synthesis of β-lapachone has been accomplished in eight steps with an overall yield of twenty-three percent starting from alpha-naphthol. The yields from the various steps were sufficiently good to insure that the derivatives of β-lapachone which might be effective against Chagas' disease could be obtained in reasonable amounts.
    β-拉帕酮的合成已从8个步骤完成,从α-萘酚开始的总产率为23%。来自各个步骤的产率足够好以确保可以合理量获得可能有效对抗恰加斯氏病的β-拉帕酮衍生物。
  • Synthesis and reactivity of some 4-bromo- 2H-chromenes and 2H-thiochromenes
    作者:Christopher D Gabbutt、David J Hartley、John D Hepworth、B.Mark Heron、Magan Kanjia、M.Moshfiqur Rahman
    DOI:10.1016/s0040-4020(01)86967-2
    日期:1994.2
    synthesis of 4-bromo- 2H-chromenes and 2H-thiochromenes and of 1-bromo-3,4-dihydronaphthalene from the corresponding ketones and PBr3 is described. In some instances, significant quantities of the phosphonic acids (3) are isolated. Conversion of the bromo compounds to the lithio derivatives provides access to a wide range of novel 4-substituted 2H-chromenes and 2H-thiochromenes.
    描述了由相应的酮和PBr 3容易地合成4-溴-2 H-色烯和2 H-硫代色烯以及1-溴-3,4-二氢萘。在某些情况下,分离出大量的膦酸(3)。溴化合物向硫代衍生物的转化提供了广泛的新颖的4-取代的2 H-色烯和2 H-硫代色烯的途径。

    This invention relates to compositions, and related compounds and methods, of conjugates of synthetic nanocarriers, or components thereof, and biologically active agents, such as immunomodulatory agents, antigens, anticancer agents or antiviral agents. The biologically active agents are released from the synthetic nanocarriers in the presence of a reducing agent or by reaction with a thiol.

  • A mild and convenient one-pot photochemical synthesis of chroman-4-one derivatives. The photo-Fries rearrangement of (hetero)aryl 3-methyl-2-butenoate esters under basic catalysis
    作者:Cecilia Samaniego López、Rosa Erra-Balsells、Sergio M. Bonesi
    DOI:10.1016/j.tetlet.2010.06.063
    日期:2010.8
    catalysis-mediated photo-Fries rearrangement reaction of aryl 3-methy-2-butenoate esters in room temperature cyclohexane—10% KOH system was investigated. This mild photochemical reaction leads to the formation of chroman-4-one derivatives in good to high yield and in short reaction times (30–120 min) in a one-pot photochemical reaction. Also, the photochemical reaction, as a convenient, versatile, and general
    研究了3-甲基-2-丁烯酸酯芳基在室温环己烷-10%KOH体系中的双相催化介导的光-弗里斯重排反应。这种轻度的光化学反应导致一锅法光化学反应中生成高价至高产率的苯并吡喃-4-酮衍生物,反应时间短(30-120分钟)。同样,作为一种方便,通用和通用的方法,光化学反应可有效地应用于多环和杂环的3-甲基-2-丁烯酸酯。
