Direct reaction of isocyanides with some sulfenic-acid-generating sulfoxides led to the effective formation of the corresponding thiocarbamic acid S-esters in good to high yields. A multicomponent reaction involving isocyanide, sulfoxide, and a suitable nucleophile has also been developed, providing ready access to a diverse range of sulfur-containing compounds, including isothioureas, carbonimidothioic acid esters, and carboximidothioic acid esters.

A silver-catalyzed chemoselective [4+2] annulation of aryl and heteroaryl isocyanides with α-substituted isocyanoacetamides was developed for the facile and efficient synthesis of 2-aminoquinolones, naphthyridines, and phenanthrolines. A mechanism for this multistep domino reaction is proposed on the basis of a13C-labeling experiment, according to which an unprecedented chemoselective heterodimerization of two different isocyanides generates an α-amidoketenimine intermediate, which undergoes 1,3-amino migration to form an α-imidoylketene, followed by 6 π electrocyclization.

A series of selenazolopyridine derivatives have been synthesized and characterized by X-ray diffraction, high resolution NMR and Mass spectrum. The in vitro anticancer activities of the synthetic compounds were screened against a panel of human cancer cell lines, human breast carcinoma MCF-7 cells, human liver carcinoma HepG2 cells and L02 normal cell line by MTT assay. By analyzing the structure-activity relationship among the synthetic compounds, it was found that 2-(phenylamino) selenazolo [5,4-b] pyridine, (PSeD, 7) had higher growth inhibitory effect on MCF-7 cells. The intracellular mechanism of cell death was evaluated by flow cytometric analysis and ROS assay, which revealed that PSeD could induce MCF-7 cells apoptosis by scavenging intracellular ROS. Taken together, we regard PSeD as an antioxidant which could inhibit cancer cell growth through induction of apoptosis.
