A novel synthetic approach towards N-phenylsuccinimides from γ-lactam-2-carboxylic acid derivatives by reaction with CAN–NaBrO3
摘要:
N-Arylsuccinimides have been synthesized by decarboxylative oxidation of N-aryl-gamma-lactam-2-carboxylic acids with the dual oxidant CAN/NaBrO(3) in refluxing acetonitrile-water. (C) 2008 Elsevier Ltd. All rights reserved.
ready-stock aryl carboxylicacids has been developed based on weak carboxylate-directed ortho-C–H alkylation and concomitant decarboxylation processes, fabricating 3-aryl succinimides, a recurrent scaffold in drug molecules, in high yields (up to 97%). The protocol features operational simplicity, avoids the need for precious metal additives/oxidants, and offers broad substrate scope with formal meta- and
