Intramolecular Pd(0)-Catalyzed Reactions of β-(2-Iodoanilino) Carboxamides: Enolate Arylation and Nucleophilic Substitution at the Carboxamide Group
摘要:
Two different reaction pathways, the enolate arylation and the acylation of the aryl halide, can be promoted by a Pd(0) catalyst starting from beta-(2-iodoanilino) carboxamides. The intramolecular acylation of beta-(2-iodoanilino) carboxamides reported here is the first example of a nucleophilic attack of a sigma-arylpalladium species at the carboxamide group, a framework that is usually inert toward organopalladium reagents.
Compounds of formula (I) or pharmaceutically acceptable salts thereof, exhibit 5-HT

agonism in addition to noradrenaline reuptake inhibition and optionally also 5-HT reuptake inhibition are useful for the treatment of obesity.
