Abstract
An operationally mild and efficient synthesis of benzothiazolopyrimidine is achieved by a three-component reaction of 2-aminebenzo[d]thiazoles, sulfonyl azides and terminal ynones. This cascade process involved a CuAAC/ring cleavage/cyclization reaction. Particularly, most of the benzothiazolopyrimidine derivatives could be isolated by filtration without further purification.

Abstract
A new efficient and stereoselective synthesis of 12-tetrazolyl substituted (E)-5H-quinazolino[3,2-a]quinazolines via sequential Ugi-azide/Staudinger/aza-Wittig/addition/Ag(I)-catalyzed cyclization was developed. The four-component reactions of 2-azidobenzaldehyde, 2-(alkynyl)benzenamine, isocyanide, and trimethylsilyl azide gave Ugi-azide intermediates, which were subsequently treated with triphenylphosphine and isocyanate to produce 12-tetrazolyl substituted (E)-5H-quinazolino[3,2-a]quinazolines in the presence of Ag(I) catalyst and K2CO3.

Abstract
A modular approach to a polyfunctionalized 5H-indolizino[3,2-b]indole, an indolizine-indole fused system, was achieved from readily available pyridine-2-acetonitrile, 2-bromobenzaldehyde, and TMSCN via the strategic combination of a one-pot three-component assembly and Cu-catalyzed Ullmann-type double C-N coupling reactions through which five new bonds (two C-C and three C-N) were formed in two steps.

Abstract
A concise and efficient approach to prepare dihydro-1,4-benzothiazine derivatives is described via oxidative ring-expansion of 2-aminobenzothiazoles with olefins under metal-free conditions. This protocol is applicable for a wide range of readily accessible 2-aminobenzothiazoles and olefins with moderate-to-good yields. The [4+2] heteroannulation between the intermediacy of oxidative ring-opening of 2-aminobenzothiazoles and olefins is suggested to rationalize the formation of the product.

Abstract
Herein, we present a tandem aza-Michael addition-vinylogous aldol condensation strategy for the synthesis of N-bridged pyridine fused quinolone derivatives from quinolones and ynones. The presented tandem transformation features the construction of C-N and CC bonds in a single operation, under transition metal-free conditions. The wide substrate scope and gram scale synthesis of pyridine fused quinolone derivatives expand the synthetic value of the presented protocol.

Abstract
Herein, we present a copper-catalyzed tandem reaction of 2-aminoimidazolines and ortho-halo(hetero)aryl carboxylic acids that causes the regioselective formation of angularly fused tricyclic 1,2-dihydroimidazo[1,2-a]quinazolin-5(4H)-one derivatives. The reaction involved in the construction of the core six-membered pyrimidone moiety proceeded via regioselective N-arylation-condensation. The presented protocol been successfully applied to accomplish the total synthesis of TIC10/ONC201, which is an active angular isomer acting as a tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL): a sought after anticancer clinical agent.

Abstract
NHC-Catalyzed intramolecular benzoin condensation-oxidation is developed for the expedient synthesis of diverse cyclic 1,2-diketones incorporated in dibenzo-fused seven-membered heterocycles in good to excellent yields, under ambient conditions. The presented carbene-catalyzed transformation appears to proceed through the benzoin intermediate followed by aerobic oxidation.
