The photochemical reactivity involves an excited state reaction that provides convenient access to bicyclic compounds. The disclosed reactivity is a new photochemical pathway involving 1,3-dicarbonyl compounds and amines as well as for enaminones.
专利号:US-5329022-A 优先权日:1991-01-16 标 题:Process for the synthesis of citraconimides 发明人:TALMA AUKE G; HOOFT HENDRIKA P M; VAN DE BOVENKAMP-BOUWMAN ANNA 权利人:AKZO AMERICA INC 摘要:The present invention relates to an improved synthesis method for the making of citraconimides wherein a citraconic anhydride is reacted with 0.5 to 2.0 equivalents of at least one amine salt. This process may be carried out in a solvent and generally leads to excellent yields of the citraconimides with high selectivity and easy purification. The present inventional so relates to a process for the production of citraconic anhydride from itaconic anhydride with an amine or phosphine catalyst and in a cosolvent.
