  • A photochemical ring expansion of 6- to 8-membered nitrogen heterocycles by [1,3]-sigmatropic rearrangement
    作者:Morgan A. Manning、Wei Sun、Mark E. Light、David C. Harrowven
    DOI:10.1039/d1cc00393c
    日期:——
    route to azocines and benzoazocines from furopyridinones is described through a photochemically induced [1,3]-sigmatropic rearrangement. The method gives access to these 8-membered nitrogen heterocycles from dimethyl squarate in four stages and with excellent atom economy by sequencing thermal and photochemical ring expansion steps under continuous flow.
    通过光化学诱导的[1,3] -sigmatropic重排描述了一种从呋喃并吡啶类向偶氮素和苯并偶氮素的新途径。通过在连续流动下对热和光化学扩环步骤进行排序,该方法可分四个阶段从方酸二甲酯获得这些8元氮杂环,并且具有出色的原子经济性。
  • A Thermally Induced Hydride Transfer from an Amine to an Allene Triggers an Annulation Reaction, Giving Dihydrofuropyridinones
    作者:Wei Sun、Dharyl C. Wilson、Mark E. Light、David C. Harrowven
    DOI:10.1021/acs.orglett.8b01792
    日期:2018.7.20
    A thermal rearrangement leading to dihydrofuropyridinones and related polycyclic ring systems from furanones and cyclobutenones is described. A key feature of the reaction is the thermally induced hydride transfer from a 3°-amine to a conjugated allene to trigger cyclization.

  • <i>tert</i>-Butyl Substituent as a Regiodirecting and Novel C−H Protecting Group in Cyclobutenedione-Based Benzannulation Chemistry
    作者:Fuqiang Liu、Lanny S. Liebeskind
    DOI:10.1021/jo971565p
    日期:1998.5.1
    2-Unsubstituted hydroquinone monoacetates, quinones, and 3-unsubstituted quinolizinones were synthesized in moderate to high yields via tert-butyl and trimethylsilyl substituted cyclobutenediones. The addition of unsaturated carbon nucleophiles proceeded regiospecifically at the carbonyl group most distant from the tert-butyl or trimethylsilyl substituent. Thermolysis of the adducts, followed by treatment under acidic conditions to remove the tert-butyl and trimethylsilyl groups in good overall yields, provided access to a variety of "less-substituted" hydroquinone monoacetates, quinones, and quinolizinones. Of the two systems, the tert-butyl-substituted cyclobutenediones proved the most useful.
