Novel transformation of aryl 2-iodophenyl ketones into 1,3-diarylisoquinolines with (TMS)2NH, styrenes, NIS, and tBuOK

Treatment of aryl 2-iodophenyl ketones with TMS2NH in the presence of Sc(OTf)3 at warming conditions, followed by the reaction with styrenes and NIS gave N-(1-aryl-2-iodoethyl) aryl 2-iodophenyl ketimines. Further treatment of N-(1-aryl-2-iodoethyl) aryl 2-iodophenyl ketimines with tBuOK in the presence of 1,10-phenanthroline at 120 °C generated 1,3-diarylisoquinolines in moderate yields through SET from tBuOK onto the iodophenyl group to form aryl radicals, their 6-endo-trig cyclization onto the vinyl groups, and aromatization of the cyclized intermediates. The present method is a novel approach for the preparation of the isoquinoline core via two steps from aryl 2-iodophenyl ketones.

One-Pot Synthesis of Spirocyclopenta[ a]indene Derivatives via a Cascade Ring Expansion and Intramolecular Friedel-Crafts-Type Cyclization

A one-pot efficient synthetic approach for the rapid construction of spirocyclopenta[a]indene derivatives has been developed via an iodine-initiated cascade ring expansion and intramolecular Friedel-Crafts-type cyclization from propargyl alcohol-tethered alkylidenecyclobutanes under mild conditions with broad substrate scope. This cascade process can be elegantly conducted on a gram scale. A plausible reaction mechanism has been proposed on the basis of a series of deuterium labeling and control experiments.

Visible Light Induced Cyclization to Spirobi[indene] Skeletons from Functionalized Alkylidienecyclopropanes

In this paper, we revealed a metal-free and visible light photoinduced method for the rapid construction of spirobi[indene] skeletons, providing a simple and efficient way for easy access to spirobi[indene] scaffolds under mild conditions along with a broad substrate scope and good functional group tolerance.

Rapid construction of cyclopenta[: B] naphthalene frameworks from propargylic alcohol tethered methylenecyclopropanes

We have developed a new synthetic methodology for the rapid construction of cyclopenta[b]naphthalene frameworks from the reaction of propargylic alcohol tethered methylenecyclopropanes with mesyl chloride in the presence of triethylamine through cascade cyclization. The reaction can be performed under mild conditions without the use of transition metals, affording the target products in moderate to good yields, and this cyclization reaction process can be scaled up to a gram-scale synthesis.

Synthesis of Diiodinated All-Carbon 3,3′-Diphenyl-1,1′-spirobiindene Derivatives via Cascade Enyne Cyclization and Electrophilic Aromatic Substitution

A synthetic method for the construction of diiodinated all-carbon spirobiindene derivatives has been developed from the reaction of propargyl alcohol-tethered alkylidenecyclopropanes with iodine. The reaction proceeded through an iodination-initiated cascade intramolecular enyne cyclization and electrophilic aromatic substitution reaction process in 1,2-dichloroethane upon heating, giving desired spirocyclic products in moderate to excellent yields. Further transformation of the obtained products has also been presented.

A palladium-catalyzed reductive and carbonylative cyclization of ortho-iodo-tethered methylenecyclopropanes (MCPs) using N-formylsaccharin as CO source has been developed, affording the desired indanone derivatives in moderate to good yields with high regio- and stereoselectivity and good functional group compatibility.

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.

Copper-catalyzed cascade cyclization of 1,5-enynes: Via consecutive trifluoromethylazidation/diazidation and click reaction: Self-assembly of triazole fused isoindolines

Copper-catalyzed cascade cyclization of 1,5-enynes with two types of hypervalent reagents was developed via consecutive trifluoromethylazidation/diazidation and intramolecular click reaction (CUAAC), providing one-pot self-assembly of triazole fused isoindolines bearing a trifluoromethyl or an azide moiety. Moreover, the construction of a trifluoromethylcyclopropyl unit, which has been considered as a metabolically stable replacement for a tert-butyl moiety and was difficult to access, was also achieved under trifluoromethylazidation conditions. All these reactions exhibited excellent chemoselectivity, good to excellent yields and broad functional group tolerance.
