Aryne 1,2,3-Trifunctionalization with Aryl Allyl Sulfoxides
2016-08-15T00:00:00Z (GMT) by
An aryne 1,2,3-trisubstitution with aryl allyl sulfoxides is accomplished, featuring an incorporation of C–S, C–O, and C–C bonds on the consecutive positions of a benzene ring. The reaction condition is mild with broad substrate scope. Preliminary mechanistic study suggests a cascade formal [2 + 2] reaction of aryne with SO bond, an allyl S → O migration, and a Claisen rearrangement.
