Abstract:Structurally diverse novel 1,4-benzodiazepine analogues related to selective CCKA antagonist MK-329, and CCKB antagonists L-365,260 and YM022 are prepared via palladium-catalyzed three component domino reactions involving allenylation-carbonylation-anion capture in one-pot cascade protocol in good to excellent yields.
Keywords:Benzodiazepines  Cholecystokinin (CCK) receptor  Palladium  Allenylation  Carbonylation
