| In continuation of our studies on the development of novel methods for the synthesis of heterocycles we found that phosphatyloxy-substituted alkynyl ketones 1 and imines 2 undergo facile Cu-catalyzed cycloisomerization reaction with concomitant 1,3-migration of phosphatyloxy group to form furans 3 and indolizines 4 in good yield. It was also found that phosphatyloxy heterocycles 3 and 4 can be efficiently functionalized via Kumada cross-coupling protocol to give alkyl- and aryl-substituted derivatives 5 and 6, respectively. |
