A Concise Synthesis of 6,7-Dihydro-5H-dibenz[c,e]azepin-5-one
摘要:
A concise and efficient strategy for the synthesis of dibenz[c,e]azepin-5-ones has been developed. The approach relies on a key transformation involving Suzuki-Miyaura coupling of 2-bromobenzyl azides with 2-(methoxycarbonyl)phenylboronic acid, followed by either a stepwise sequence involving Staudinger reaction and lactam formation or one-pot hydrogenation/base-mediated intramolecular lactam formation.

An unprecedented and convenient synthetic approach to 2,3-dihydro-1H-isoindol-1-one (isoindolinone) derivatives has been developed. The key and final step of the method is the reaction of N-alkyl-N-(o-bromobenzyl)benzamides with butyllithium in THF at −78 °C. The corresponding 2-alkyl-3-aryl-2,3-dihydro-1H-isoindol-1-ones were produced in moderate-to-fair yields, probably via oxidation of the initially
