Ligand Free

We have demonstrated the first ligand free CuI-nanoparticle catalyzed N-arylation of amides/cyclic amides in an ethylene glycol/2-propanol solvent system under mild conditions. This is further extended for one pot synthesis of benzimidazole, and quinazolinone via intermolecular amidation followed by cyclization.

One Pot Synthesis

A highly efficient and generally applicable protocol, starting from 2-bromobenzamides and 2-bromo(thio)phenols via twice copper-catalyzed couplings to afford dibenzothiazepines and dibenzoxazepinones has been developed. High levels of yield and chemoselectivity are achieved in a single-pot reaction by using an appropriate ligand. Moreover, this facile methodology allows rapid access to a variety of bio­active compounds and known psychotropic drug, which should broaden its application in organic synthesis.

In the presence of Cs2CO3, the first simple, efficient, and one-pot procedure for the synthesis of 3,5-diaryl pyridines via a variety of aromatic terminal alkynes with benzamides as the nitrogen source in sulfolane is described. The formation of pyridine derivatives accompanies the outcome of 1,3-diaryl propenes, which are also useful intermediates in organic synthesis. Thus, pyridine ring results from a formal [2+2+1+1] cyclocondensation of three alkynes with benzamides, and one of the alkynes provides one carbon, whilst benzamides provide a nitrogen source only. A new transformation of alkynes as well as new utility of benzamide are found in this work.
