This invention relates to novel isonitriles, including arylsulfonyl isonitriles, and methods for their synthesis. The isonitriles include a conjugated ring system. The structure is designed with the flexibility to have multiple substitution patterns. The isonitriles may be used in applications including, but not limited to, pharmaceutical compositions.

Alkylsulfinates function as formalnucleophiles in Mannich-type reactions to give sulfonyl formamides, which are readily dehydrated to the corresponding sulfonylmethyl isonitriles. The efficient, two-step synthesis provides a general route to sulfonylmethyl isonitriles from readily available methyl sulfinates or thiols. Mechanistic analysis reveals that the unusual nucleophlicity of the alkyl sulfinates
