Abstract
AbstractA 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.
