Synthesis of 3-Methylthioindoles via Intramolecular Cyclization of 2-Alkynylanilines Mediated by DMSO/DMSO-d6 and SOCl2

The intramolecular cyclization of 2-alkynylanilines mediated by DMSO/SOCl2 was found to afford biologically interesting 3-methylthioindoles, which are rarely obtained by the exiting methods. DMSO could also be replaced with its deuterated count

Cu(OAc)2-Mediated Cascade Annulation of Diarylalkyne Sulfonamides through Dual C-N Bond Formation: Synthesis of 5,10-Dihydroindolo[3,2-b]indoles

An unusual cascade reaction featuring annulation of diarylalkyne sulfonamides to form 5,10-dihydroindolo[3,2-b]indoles has been realized with Cu(OAc)2 as the sole oxidant. This unprecedented process encompasses two sequential C-N bond formation

Quadri-synergetic effect for highly effective carbon dioxide fixation and its application to indoloquinolinone

The first copper-catalyzed cyclic anti-nucleometallation-carboxylation of 2-alkynylanilines with carbon dioxide in the presence of dimethylzinc (ZnMe 2) and cesium fluoride (CsF) for the effective synthesis of indolyl-3-carboxylic acids and indolodihydropyran-2-one is described. Through a mechanistic study, it is unveiled that the metal ions Cu2+, Zn 2+, Cs+ and F- are working together for this CO2-based highly efficient carboxylation. Copyright
