) or unsubstituted benzene ring and the 1-position of the piperidine ring has an acyl group [—C(═O)—R
4
], or a pharmaceutically acceptable salt thereof has an excellent sodium channel inhibition action and an excellent analgesic action and shows a high analgesic effect particularly to neurogenic pain. The present compound is useful as a sodium channel inhibitor of low side effect
Herein, we report an efficient photoinduced iron-catalyzed strategy for cross-couplings of alkyl carboxylic and acrylic acids, which provides a powerful tool for the synthesis of a variety of alkenes with polar functional groups. This novel synthetic methodology can also be applied to the preparation of ketones by using α-keto acids. Mechanistic experiments revealed preliminary mechanistic details
