title: Pd(0)-catalyzed regio- and stereoselective cyclization of alkynes: selective synthesis of (E)-4-(isobenzofuran-1(3H)-ylidene)-1,2,3,4-tetrahydroisoquinolines and aze/oxepinoindoles.
abstract: 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.
