Intermolecular Cyclization

A series of 6-substituted benzo[b]thiophenes was synthesized using a Sc(OTf)3-catalyzed intermolecular cyclization between para-substituted N-(arylthio)succinimides and alkynes taking advantage of a unique and selective 1,2-sulfur migration occuring via an electrophilic ipso cyclization to a key spirocyclic thiete intermediate.

Intermolecular Cyclization

Synthesis of seven-membered carbocycle-fused aromatics was realized by Catellani reaction using terminally brominated alkyl carbagermatranes through intermolecular cyclization manner. Various functional groups were well tolerated, and this transformation was also expanded to the synthesis of carbocycles of other size. The utility of this method was demonstrated by modification of natural product derivatives and synthesis of bioactive molecules.
