Abstract

The novel method for the synthesis of gem-bisarylthio enamines and α-phenylthio ketones was developed via the coupling of α-substituted vinyl azides with thiols in the presence of tetrabutylammonium iodide (TBAI) as a redox catalyst and electrolyte at room temperature. Electronic properties were crucial in the generated products. This protocol features metal- and oxidant-free materials, broad tolerance of substrates, and mild reaction conditions.

Abstract

An efficient approach has been developed for the construction of quinazolin-4(3H)-ones by the selective anodic dehydrogenative oxidation/cyclization of benzylic chlorides and 2-aminobenzamides. The method features acceptor-free and metal-free dehydrogenation of amines to imines; a subsequent intermolecular addition provides the products in moderate to good yields.

Abstract

A new method for the synthesis of multisubstituted guanidines through tandem intermolecular insertion of isonitriles with un­activated amides has been developed. In this study, isonitriles could be used not only as reaction materials but also as the source of amines.
