Three-Component Castagnoli-Cushman Reaction of 3-Arylglutaconic Acid Anhydrides, Carbonyl Compounds, and Ammonium Acetate: a Quick and Flexible Way to Assemble Polysubstituted NH-δ-lactams

A practical straightforward synthesis of medicinally important NH-δ-lactams through the three-component Castagnoli-Cushman reaction of 3-arylglutaconic anhydrides with carbonyl compound and ammonium acetate has been developed. The scope of the protocol has been thoroughly explored paying particular attention to the carbonyl component using wide array of aliphatic and aromatic aldehydes as well as rarely involved cyclic and acyclic ketones. Synthetic potential of prepared compounds was demonstrated by a series of post-modifications, including unexpected isomerization.

Method for synthesizing pentene dianhydride compound by using carbon dioxide

The invention belongs to the technical field of fine chemical synthesis, and relates to a method for synthesizing a pentene dianhydride compound by using carbon dioxide. The method comprises the following steps: using a 2-butenoic acid derivative as a raw material; adding an organic alkali and a reaction solvent, introducing carbon dioxide, stirring at 0-50 DEG C to react for 0.5-24 hours, standing to room temperature after the reaction is finished, slowly releasing unreacted gas, directly concentrating the reaction solution under reduced pressure to obtain a crude product, and carrying out column chromatography or recrystallization purification to obtain the pentene dianhydride product. According to the method, the 2-butenoic acid derivative and carbon dioxide which are cheap and easily available are used as raw materials, organic alkali is used as an accelerant, and the method is safe and simple to operate, low in toxicity and environment-friendly and has potential application valuein fine organic synthesis of medicines, pesticides and the like.
