Palladium-catalyzed highly regio- and stereoselective 6-exo-dig and 7-endo-dig cyclization of functionalized propargylic compounds has been developed for the synthesis of (E)-4-(isobenzofuran-1(3H)-ylidene)-1,2,3,4-tetrahydroisoquinolines and aze/oxepinoindoles.
在钯催化下,功能化丙炔化合物发生了高度区域和立体选择性的 6-exo-dig 和 7-endo-dig 环化反应,从而合成了 (E)-4-(异苯并呋喃-1(3H)-亚基)-1,2,3,4-四氢异喹啉和氮杂环吲哚。
