COMPOSITION, SYNTHESIS, AND USE OF NEW ARYLSULFONYL ISONITRILES

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.

Methyl sulfinates as electrophiles in friedel-crafts reactions. Synthesis of aryl sulfoxides

The Friedel-Crafts reaction of methyl alkyl- and arylsulfinates with aromatic systems, activated by one or more electron-donating substituents (OH, OMe, NHR, NR2), provides alkyl aryl and diaryl sulfoxides under mild conditions and in moderate to good yields. The very high regioselectivity usually observed in these sulfinylation reactions is rationalized on the basis of a Wheland intermediate having a trigonal bypyramidal structure in which steric and electronic interactions are significant factors strongly destabilizing the attack to the ortho positions.
