place in the reaction of methylketones or active methylene compounds with DMF-DMA (N,N-dimethylformamide dimethyl acetal). L-Proline serves as an efficient organocatalyst in the covalent and noncovalent synchronous mode for the ambiphilic activation of various aryl, heteroaryl, and styryl methylketones, cyclic ketones, and 1,3-diketones with DMF-DMA to achieve the convenient syntheses of the versatile

An efficient protocol for the construction of 3‐carbonyl functionalized 4‐pyrones has been developed using a transition‐metal free thermal cascade reaction of diazodicarbonyls with β‐enamino esters or β‐enamino ketones. This reaction proceeds via cascade carbene generation, ketene formation via thermal Wolff‐rearrangement, nucleophilic addition, intramolecular cyclization, and elimination. This protocol
