A new radical cyclization has been developed for the one-step synthesis of spiro dihydroisoquinolinone derivatives from alicyclic amino acids bearing N-(2-phenyl)benzoyl groups through photoinduced electron transfer (PET)-promoted decarboxylation. Reductive ipso-radical cyclization onto a benzene ring by an alkyl radical is achieved under mild conditions for the first time, although the substrates are limited to five-membered aliphatic carboxylic acids bearing N-(2-phenyl)benzoyl groups.

The invention provides a method for preparing an amide compound by photocatalysis of a nitrogen-containing heterocyclic compound. The method comprises the following steps: mixing the nitrogen-containing heterocyclic compound, organic carboxylic acid and tetrahalomethane in a solvent, adding a catalyst, and reacting under the illumination condition to prepare the amide compound. According to the invention, the organic carboxylic acid, the nitrogen-containing heterocyclic compound containing reactive hydrogen on nitrogen atoms and the tetrahalomethane are used as raw materials, so the raw materials are wide in source, low in cost and high in safety, and large-scale production is facilitated; the halogen simple substance is co-produced in the reaction process, the added value is high, a large amount of waste is prevented from being generated, and the method has high atom economy and environmental friendliness; light conditions are adopted to replace traditional heating and high-pressure conditions, the reaction conditions are mild, environmental pollution is reduced, and the reaction cost is reduced; the method has the advantages of good substrate applicability, mild process conditions, environmental protection, simple process, simple and feasible operation method, and facilitation of popularization and application.
