Cu(I)-Catalyzed Coupling and Cycloisomerization of Diazo Compounds with Terminal Yne-Alkylidenecyclopropanes: Synthesis of Functionalized Cyclopenta[ b]naphthalene Derivatives

A Cu(I)-catalyzed coupling and cycloisomerization of diazo compounds with terminal yne-alkylidenecyclopropanes (ACPs) has been presented. This reaction starts from the formation of an allenic intermediate in the Cu(I)-catalyzed cross-coupling reaction of a diazo compound with terminal alkyne in yne-tethered ACP and then undergoes a domino cycloisomerization of a 6π-electrocyclization and cyclopropane ring-opening rearrangement to give functionalized cyclopenta[b]naphthalene derivatives in moderate to excellent yields under mild conditions.

Reactions of iodinated vinylidene complexes generated from 1-Iodo-1-alkynes and W(CO)5(thf)

We have succeeded in generating iodinated tungsten vinylidene complexes from 1-iodo-1-alkynes and W(CO)5(thf), and have employed these complexes for two types of synthetically useful reactions, that is, 6π-electrocyclization for o-(iodoethynyl)
