Approaches to Bridged Thiaannulenes

The macrocyclic trisulphide (5) has been prepared from 2,5-bis-(p-bromomethylphenylmethylthiomethyl)thiophen (7) but attempts to convert it into the triolefin (2) via a Stevens rearrangement of the derived trimethylsulphonium salt and elimination of sulphur were frustrated by the intractability of the salt.In other experiments 15,17-dimethyl-16-thiabicycloheptadeca-2,12,14,17-tetraen-6,8-diyne (9) was prepared but attempted base-catalysed rearrangement to the bridged thia-annulene 15,17-dimethyl-16-thiabicycloheptadeca-2,4,6,8,10,12,14,17-octaene (8) led to a product of uncertain structure.
