Metal-catalyzed cyclizative cross-coupling reactions have attracted enormous attention due to their unique cascade nature. We demonstrated, herein, a dual-cyclizative coupling of ynone oxime ethers with acrylamides for the synthesis methylene-linked isoxazolyl 2-oxindoles. The was triggered by palladium(II)-catalyzed ether cyclization, which underwent Heck-type intercepted an aryl iodide insertion. Control experiments were carried out understand mechanism.

A novel metal-free annulation of ynamides with 2H-azirines catalyzed by BF3·Et2O is described, leading to the construction polysubstituted 2-aminopyrroles in a facile, flexible, and atom-economical way. This synthetic strategy proceeds efficiency, broad substrate scope, short reaction time under mild conditions. Furthermore, obtained products could be modified generate diverse 2-iminopyrrole frameworks high yields.

Isocyanide is an intriguing one-carbon synthon that frequently employed in a variety of carbon-carbon and carbon-heteroatom bond-forming reactions. Isocyanide-based multicomponent reactions (IMCRs) are effective synthetic tools organic synthesis for the preparation complex heterocyclic molecules. The IMCRs water have become attractive research direction, enabling simultaneous growth both green solvents towards ideal synthesis.

A novel approach for the production of halogen cations through reaction halogens with silver ions is described in this paper. On basis, regioselective synthesis 3-haloquinolines and 3-halospirocyclohexadienones realized solvent regulation. The gram-scale compatibility complex substrates demonstrate synthetic potential protocol, which will be an appealing strategy organic synthesis.
