  • Visible-Light-Promoted Polysubstituted Olefins Synthesis Involving Sulfur Ylides as Carbene Trapping Reagents
    作者:Cong Ye、Bao-Gui Cai、Juan Lu、Xiao Cheng、Lei Li、Zhong-Wen Pan、Jun Xuan

    日期:2021.1.1
    A blue-light-emitting diode (LED) promoted coupling of aryl diazoacetates with sulfur ylides is described. This protocol features mild conditions, good functional group tolerance, and broad substrate scope for both aryl diazoacetates with sulfur ylides. Under optimal reaction conditions, a wide range of trisubstituted olefins is obtained in moderate to good yield, which can be further transferred to

    A Lewis acid-promoted [6+1] annulation between sulfur ylides and modified vinyl benzoxazinanones was described. In this reaction, the newly designed vinyl benzoxazinanones could serve as a novel six-atom synthon, and the key to success is the installation of an electron-withdrawing group on the alkene moiety of the benzoxazinanones. A broad range of substrates are compatible with this mild reaction

    日期:2018.3.16
    The highly efficient and expedient route for the syntheses of 2-aroyl benzofurans has been developed via the cascade [2+2] followed by a [4+1] annulation on arynes. The overall transformation proceeded through the formation of ortho-quinone methide by the insertion of transient aryne into N,N-dimethylformamide and subsequent trapping with sulfur ylide. Moreover, this transformation has a broad range
    通过级联[2 + 2],然后在芳烃上进行[4 + 1]环化,已经开发出了2-芳酰基苯并呋喃的高效合成途径。通过将瞬时的芳烃插入N,N-二甲基甲酰胺中,然后用内鎓盐捕集,通过形成邻醌甲基化物来进行整体转化。而且,该转变具有高官能团耐受性的广泛的基板范围。该新反应已成功用于有效的CYP19芳香酶抑制剂的合成和对生物活性复合物雌酮的后期功能化。

    A simple, general route to the 2,3-dihydrobenzofurans substituted at C3 by an aryethynyl or aryl group, starting from propargylamine and its derivatives with benzoyl sulfonium salts, has been developed. This reaction involved an in situ generated o-quinone methide (o-QM) intermediate followed by [4+1] annulation with sulfur ylides. Notably, this protocol's features include moderate to excellent yields
    炔丙基胺及其衍生物与苯甲酰基sulf盐开始,已经开发了一种简单的通用路线,该路线是在C3处被炔基或芳基取代的2,3-二氢苯并呋喃。该反应涉及原位生成的邻醌甲基化物(o-QM)中间体,然后用酰化物进行[4 + 1]环化。值得注意的是,该方案的功能包括中等至优异的收率和非对映选择性(通常> 20:1 dr),易于操作,以及可通过CC和CO键形成带有乙炔基或芳基的通用2,3-二氢苯并呋喃。一锅没有任何催化剂的混合溶液。
