Abstract

Abstract 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 ...
