1′2,3,3′4,4′-Hexa-O-benzylsucrose was esterified at both terminal positions with an unsaturated acid derived from d-glucose. Cyclization of the resulting di-olefin under the RCM conditions afforded the corresponding 21-membered macrocyclic unsaturated di-ester. The same sequence of reactions performed for 6,6′-diamino-6,6′-dideoxy-1′2,3,3′4,4′-hexa-O-benzylsucrose gave a 21-membered macrocyclic unsaturated
