A synthetically simple and convenient approach to tetrasubstituted thiophenes with rare combination of the alkoxy, amino, and cyano groups has been developed. The assembly of polyfunctionalized thiophene ring is implemented in one preparative step by sequential addition of isothiocyanate and 2-bromoacetonitrile to the lithiated (with n-BuLi) alkoxyallene. The reaction proceeds through in situ formation and intramolecular cyclization of cyanomethyl 2-alkoxy-N-buta-2,3-dienimidothioate (1-aza-1,3,4-triene).

AbstractAn easy and expedient method for the one-pot synthesis of 1H-isoindole-1,3(2H)-diones has been developed by the reaction of the corresponding cyclic anhydrides with guanidinium chloride as a nitrogen source in the presence of FeCl3 as a catalyst under mild reaction conditions.

Oxidative System

A series of 2-aminothiazoles is prepared in moderate-to-good yields by the direct coupling of ketones and thiourea using I2/dimethyl sulfoxide as a catalytic oxidative system. This method avoids the preparation of lachrymatory and toxic α-haloketones and the use of an acid-binding agent, thus providing a more convenient approach to 2-aminothiazoles compared to the Hantzsch reaction.
