An interesting sequential reaction involving Pd-catalyzed coupling, propargyl−allenyl isomerization, and Alder−ene cycloaddition is reported, providing a facile synthesis of some not readily available 2,3-dihydrofurans from electron-deficient vinyl or aromatic halides and 1-aryl-prop-2-ynyl 3′-methylbut-2′-enyl ethers.
据报道,一个有趣的顺序反应涉及Pd催化的偶联,炔丙基-烯丙基异构化和Alder-ene环加成反应,可从缺电子的乙烯基或芳族卤化物和1-芳基-卤化物轻松合成一些不易获得的2,3-二氢呋喃。丙-2-炔基3'-甲基丁-2'-烯基醚。
