General description

p-Toluenesulfonylmethyl isocyanide undergoes base-promoted 1,3-dipolar cycloaddition reaction with immobilized imines under microwave irradiation to yield 1,5-disubstituted imidazoles. It is a versatile synthon in organic chemistry, extensively used for the synthesis of heterocyclic compounds.

Application

p-Toluenesulfonylmethyl isocyanide was used:
  • in the synthesis of triplet drugs with the 1,3,5-trioxazatriquinane skeleton
  • as reagent in the preparation of biologically active pyrroles and imidazoles
  • as the isonitrile component in a diastereoselective Passerini reaction employing sugar-derived aldehydes

Organic solid-state lasers are essential for various photonic applications, yet current-driven lasing remains a great challenge. Charge transfer (CT) complexes formed with p-/n-type organic semiconductors show great potential in electrically pumped lasers, but it is still difficult to achieve population

An improved synthetic method for triplet drugs with the 1,3,5-trioxazatriquinane skeleton was developed that used p-toluenesulfonylmethyl isocyanide (TosMIC) instead of 1,3-dithiane. Using the improved method, we synthesized compounds with two identical pharmacophore units and an epoxymethano group, that is, capped
