This noteworthy finding demonstrates DMSO's capability to act as a convenient surrogate for HCHO. Considering the significant role of hydroxymethylation in organic synthesis, we have explored the introduction of a hydroxymethyl group into a range of 1,3-dicarbonyl compounds using DMSO (Scheme 1). ...

Cascade reactions of 1,3-dicarbonyls with Morita-Baylis-Hillman acetates of nitroalkenes using a quinine derived chiral squaramide organocatalyst led to the formation of pyranones and pyranonaphthoquinones in good to excellent yields and high diastereoand enantioselectivities. Representative examples of th...

A simple, efficient procedure is proposed for Knoevenagel condensations of 1,3-dicarbonyl compounds with aldehydes catalyzed by heterogeneous polystyrene-supported aluminum chloride (Ps-AlCl3) under solvent-free conditions. The condensations are carried out smoothly with high yields (87–98%) at 60 °...

An electrocatalytic C–H activation method to prepare tetrasubstituted furans from 1,3-dicarbonyl compounds and allenes using Cp2Fe as a redox catalyst has been developed. This method achieves the intermolecular cyclization reaction of allenes under electrochemical conditions through the C-radical pathw...
