(Chemical Equation Presented) The synthesis of new 18-membered hexaazamacrocycles containing a functionalized 2,2′:6′,2″- terpyridine moiety as part of the cyclic backbone and three acetate pendant arms is described. The reported synthetic procedure is ba

The synthesis of various oligopyridines possessing a carboxylate and at least one bromoethyl group is reported. The bipyridine and terpyridine cores were constructed in good yields via a Stille cross-coupling, starting from bromopicolines and ethyl bromopicolinate. The bromomethyl function was obtained by free radical bromination using NBS in benzene or bromine in benzene/water biphasic mixture. The building of two model podands by nucleophilic displacement of benzylic bromine by an amine or by a phenol group is described.
Synthesis of bisfunctionalized-oligopyridines bearing an ester group

, p. 6113 - 6115 (2007/10/03)
The synthesis of 2,2′-bipyridine, 1,10-phenantroline and 2,2′:6′,2″-terpyridine substituted by an ethylester function is described. The 5- and 6-methyl-2,2′-bipyridines bearing an ethylester group on the 6′ position as well as the ethyl 6,6″-dimethyl-2,2′:6′,2″-terpyridine-4′- carboxylate moiety were synthesized via a Stille cross-coupling reaction, starting from bromo-picoline building blocks. A radical bromination of the methyl-oligopyridine gave selectively the corresponding benzylic bromide derivatives in fair yield.
