Journal ArticleDOI
PhI(OCOCF3)2-mediated C-C bond formation concomitant with a 1,2-aryl shift in a metal-free synthesis of 3-arylquinolin-2-ones.
TL;DR: This novel approach features not only metal-free oxidative C(sp(2))-C( sp(2)C(sp-2) bond formation but also an exclusive 1,2-aryl migration.
Journal ArticleDOI
Construction of 1,4-benzodiazepine skeleton from 2-(arylamino)benzamides through PhI(OAc)2-mediated oxidative C–N bond formation.
TL;DR: New compounds involving the biologically important 1,4-benzodiazepine skeleton were conveniently constructed from 2-(arylamino)benzamides through PhI(OAc)2-mediated oxidative C–N bond formation to demonstrate the flexibility to tolerate a broad scope of substrates.
Journal ArticleDOI
Primary Anion−π Catalysis and Autocatalysis

TL;DR: Computational studies on autocatalysis reveal transition state and product forming a hydrogen-bonded noncovalent macrocycle, like holding their hands and dancing on the active π surface, with epoxide opening and nucleophile being activated by anion-π interactions and hydrogen bonds to the product.
Journal ArticleDOI
Hypervalent-iodine-mediated cascade annulation of diarylalkynes forming spiro heterocycles under metal-free conditions.
TL;DR: An unusual reaction featuring the cascade annulation of internal alkynes to afford spiro heterocycles as the products has been realized for the first time with a hypervalent iodine reagent as the only oxidant.
Journal ArticleDOI
Synthesis of diversely substituted indoloquinolinones via Pd(II)/Cu(II)-mediated oxidative C-C bond formation and I(III)-mediated C-N bond formation.
TL;DR: A series of indoloquinolinones bearing different aromatic substitutents were readily synthesized starting from an aryl amine, a methyl 3-oxo-3-phenylpropanoate derivative, and methoxylamine through a series of reactions of coupling/enamination, oxidative annulation, a one-pot sequence of N-alkylation, saponification and meth oxygenamidation, and final intramolecular oxidative C-N bond formation.
