The synthesis of fused polycyclic dihydropyridincs was achieved using a cascade process comprising a Suzuki coupling, a nucleophilic cyclization and a hydrogen migration. Several functional groups are tolerated in this reaction and the methodology could be applied with Success to quinoline and isoquinoline derivatives. (c) 2006 Elsevier Ltd. All rights reserved.

Suzuki-Miyaura coupling of 2-bromopyridine 1b with 2-formylphenylboronic acid 2 under standard conditions, gives 2[4-(2-pyridin-2-yl-benzyl)-pyridin-2-yl]benzoic acid 5b. A similar reaction is observed for 2-bromo-6-methylpyridine 1c. A mechanistic rationale for these unusual observations is suggested. (c) 2007 Elsevier Ltd. All rights reserved.
