Abstract :
A new route to cyclophanes 6a,b incorporating 2,2′-bipyridine subunits has been elaborated using as the key steps (1) S-transalkylation of 6,6′-bis(methylsulfanyl)-2,2′-bipyridines 2a,b with ethyl bromoacetate resulting in the formation of 6,6′-bis[(ethoxycarbonyl)methylsulfanyl]-2,2′-bipyridines 3a,b and (2) ring-closing metathesis of the corresponding alkenyl ethers 5a,b.
Keywords :
