    PPh3-Catalyzed Domino Reaction: A Facile Method for the Synthesis of Chroman Derivatives
    摘要:
    A novel domino reaction catalyzed by triphenylphosphine was developed for synthesis of the highly functionalized chroman derivatives. The first example that the gamma-CH3 of allenoate undergoes cyclization to form chroman derivates was reported.

    Bifunctional Phosphine-Catalyzed Domino Reaction: Highly Stereoselective Synthesis of cis-2,3-Dihydrobenzofurans from Salicyl N-Thiophosphinyl Imines and Allenes
    摘要:
    A new bifunctional phosphine catalyst, (2'-hydroxy-biphenyl-2-yl)-diethylphosphane (LBBA-1), was developed for the highly stereoselective synthesis of cis-2,3-dihydrobenzofurans via an aza-Morita-Baylis-Hillman/umpolung addition domino reaction of salicyl N-thiophosphinyl Imines with electron-deficient allenes. Dual activation of both nucleophile and electrophile by the bifunctional catalyst accounts for the observed high reactivity and stereoselectivity.

    本发明属于化合物合成领域,具体提供了一种具有C2季碳中心的苯并二氢呋喃生物的制备方法,将具有双官能团化合物、α‑羰基甲酸酯溶于有机溶剂,加入六甲基亚酰胺进行反应,随后向反应体系中加入碱,继续反应,得到目的产物。本发明技术为全新的机理,基于原位形成的Kukhtin‑Ramirez加合物与双官能团化合物中极性羟基的插入反应,并采用两步一锅法合成策略发生分子内环化反应,以中等至较高的收率合成了一系列具有C2季碳中心的苯并二氢呋喃生物
  • P(<i>n</i>-Bu)<sub>3</sub>Catalyzed Reactions of Salicyl<i>N</i>-Thiophosphinyl Imines with Allenylphosphonates: Synthesis of Phosphono-Chromans
    作者:R. Rama Suresh、R. N. Prasad Tulichala、Ramesh Kotikalapudi、K. C. Kumara Swamy

    日期:2014.5
    A phosphine [P(n‐Bu)3]‐catalyzed reaction for the synthesis of phosphono‐chromans from allenylphosphonates and salicyl N‐thiophosphinyl imines has been described and compared with reactions for phosphorus‐free allenes. The products are (β,γ)‐cyclized and are obtained in good yields (57–83%). A key product is characterized by X‐ray crystallography.
    已经描述了膦[P(n- Bu)3 ]催化的从烯基膦酸酯和杨基N-代膦基亚胺合成膦酰基苯并二氢喃的反应,并将其与无丙二烯的反应进行了比较。产品经过(β,γ)环化,收率很高(57-83%)。关键产品的特征在于X射线晶体学。
  • Synthesis of Functionalized Chromans by P<sup><i>n</i></sup>Bu<sub>3</sub>-Catalyzed Reactions of Salicylaldimines and Salicylaldehydes with Allenic Ester
    作者:Yin-Wei Sun、Xiao-Yang Guan、Min Shi
    DOI:10.1021/ol102461c
    日期:2010.12.17
    P(n)Bu3-catalyzed cyclization reactions of salicylaldimines and salicylaldehydes with ethyl 2,3-butadienoate gave the corresponding functionalized chromans in moderate to good yields in THF under mild conditions. The new reaction provides a new method for the synthesis of biologically active chroman products.
