An exclusive thiophene-fused polycyclic I-conjugated 2-arylbenzo[4,5]thieno[2,3-d]thiazole skeleton was constructed via a one-pot CuCl-mediated three-component reaction, using 2-(2-bromophenyl)acetonitrile and aromatic aldehydes as substrates and elementa

The 1,4-palladium shift strategy allows the functionalization of remote C?H bonds that are difficult to reach directly. Reported here is a domino reaction proceeding by C(sp3)?H activation, 1,4-palladium shift, and amino- or alkoxycarbonylation, which generates a variety of amides and esters bearing a quaternary β-carbon atom. Mechanistic studies showed that the aminocarbonylation of the σ-alkylpalladium intermediate arising from the palladium shift is fast using PPh3 as the ligand, and leads to the amide rather than the previously reported indanone product.

An efficient and novel procedure for a copper catalyzed domino coupling reaction has been developed, which afforded various oxindoles in good to excellent yields with tolerance of various substituents. In addition, this method could be applied to synthesize horsfiline and coerulescine in few steps with high total yields. The Royal Society of Chemistry 2012.

The two important neurotransmitters dopamine and serotonin are synthesized with short PEG tethers and immobilized on a magnetic solid support. The tether is attached to the aromatic moiety of the neurotransmitters to conserve their original functional groups. This approach causes minimal alteration of the original structure with the aim of optimizing the immobilized neurotransmitters for aptamer selection by SELEX. For the dopamine derivative, the tether is attached to the aromatic core of a dopamine precursor by the Sonogashira reaction. For serotonin, a link to the indole core is introduced by a Claisen rearrangement from the allylated phenol moiety of serotonin. The tethers are azide-functionalized, which enables coupling to alkyne-modified magnetic beads. The coupling to the magnetic beads is quantified by UV spectroscopy using Fmoc-monitoring of the immobilized dopamine and serotonin derivatives.

A novel unexpected anionic domino process involving n-BuLi-induced rearrangement of 3,3-bis(methylthio) or 3-methylthio-3-aryl heteroaryl. alkyl-o-bromoarylacrylonitriles to ocyanoarylacetylenes in synthetically useful yields has been reported. The scope and generality of the reaction has been examined, and a possible mechanism has been proposed.
