Multicomponent Reactions of β-Ketosulfones and Formaldehyde in a Bio-Based Binary Mixture Solvent System Composed of Meglumine and Gluconic Acid Aqueous Solution
solvent for performing the hydroxymethylation of β‐ketosulfones with formaldehyde. The formed hydroxymethylation product could further react with a nucleophile, which allowed us to develop some one‐pot, stepwise, three‐component reactions of β‐ketosulfones and formaldehyde in this binary mixture. Particularly, a one‐pot, two‐step, sequential four‐component reaction of α‐bromo ketone, sodium benzenesulfinate
The preparation of a series of β -aminosulfones is described. Consideration of sulfone reactivity and mechanism of the condensaion are related in this report. These compounds failed to provide significant antibacterial activity.
