The invention discloses a kind of preparation methods of phenanthridines heterocyclic compounds.Using isonitrile and N (acyloxy) phthalimides as raw material, under the action of organic micromolecule catalyst, reduction quencher and alkali is added, reacts 20 24 hours obtained phenanthridines heterocyclic compounds under white light illumination.Preparation method of the present invention is the photochemical reaction of visible light-inducing, rigors of the conventional ultra-violet photochemical reaction to equipment have been broken away from, have used the clean energy resource (sunlight) of cheap household fluorescent lamp, LED light and " inexhaustible " that can effectively realize.In addition, the usual reaction condition of the photochemical reaction of visible light-inducing is mild, easily controllable, efficient and product yield high, therefore causes the extensive concern of synthesis chemists in recent years, and develop into the emphasis and hot spot of current research. |
