hetero-Diels–Alder reaction of the remote olefin functionality in dienamines has been developed by the simultaneous activation of α,β-unsaturated aldehydes and acyl phosphonates. The dual activation is based on an organocatalyst that activates both the α,β-unsaturated aldehyde, through dienamine formation, and the acyl phosphonate by hydrogen-bonding. The enantioselective reaction results in the formation

To develop new antibiotics owning a special mechanism, we used the molecular assembly method to synthesize a series of novelpleuromutilinderivatives containing a cinnamic acid scaffold at the C‐14 side chain. We evaluated their antibacterialactivity and used in silico molecular docking to study their binding mode with the target. The structure–activity relationship (SAR) study suggested that compounds

catalytically introduce deuterium in synthetically useful yields ortho to a carboxylic acid directing group on arenes typically requires D2 or high catalyst loadings, which makes using these approaches cost prohibitive for large-scale synthesis (equipment and reagent costs respectively). Herein, we present a simplified approach using low catalyst loadings of cationic RhIII and D2O as both deuterium source and solvent
