Presented herein is a condition-controlled selective synthesis of pyrazolonyl
spirodihydroquinolines or pyrazolonyl spiroindolines through formal [5+ 1] or [4+ 1] …

This review introduces the application of a transient directing strategy in cyclization reactions
via C–H activation. The types of cyclization reactions include C–H activation/intramolecular …

Transition-metal-catalyzed C (sp2)–H bond functionalization is recognized as a
revolutionized strategy for mainstream organic synthesis to forge structurally complex …

In light of the extensive applications of sulfur-containing heterocyclic compounds in drug
discovery, agrochemicals, and advanced materials, the construction of complex sulfur …

Bridged isoxazolidines were synthesized via Rh (III)-catalyzed C–H allylation of α-aryl
nitrones with 5-methylene-1, 3-dioxan-2-one. The nitrone group serves as a directing group …

A novel and efficient approach for the amine-directed dehydrogenative C (sp2)–C (sp3)
coupling of arylamines with acetonitrile was reported by using FeCl2 as the catalyst …

Transition-metal-catalyzed oxidative C–H olefination/annulation reactions are among the
most attractive topics in organic synthesis to construct heterocyclic compounds. The …

A Rh (III)-catalyzed C–H bond activation and subsequent [4+ 1] annulation of benzamides
with vinyl cyclic carbonates have been developed for the synthesis of isoindolinones, in …

A catalyst‐based switchable regioselective C− H activation/annulation of acrylamides with
propargyl carbonates has been developed, delivering C5 or C6 alkenyl substituted 2 …

Chemo-and regioselective Cp* Rh-catalyzed tunable [4+ 1]/[4+ 3] cyclization of free 1-
naphthylamines with propargyl carbonates has been accomplished by regulating the …
