reaction of aliphatic acyclic α,α′-dibromoketones with primary amines gave rise to α-iminoketones and α-diimines. Both reaction products could be selectively obtained under appropriate reaction conditions. Sterically hindered α,α-dibromoketones did not react with primary amines, although, under forcing conditions the Favorskii rearrangement could be induced. In aqueous methanol, α,α′-dibromoketones reacted

The rhodium(III)-catalyzed direct cross-coupling reaction of electron-deficient acrylamides with maleimides is described. This protocol displays broad functional group tolerance and high efficiency, which offers a new opportunity to access highly substituted succinimides. Dependent on the substituent positions of acrylamides and reaction conditions, olefin migrated products were obtained with high

access a series of racemic 2,3-dihydroxy-3-(N-substituted carbamoyl)propylphosphonic acidderivatives, designed to contain structural features common to both the natural substrate 1-deoxy-D-xylulose 5-phosphate (DOXP) of the Plasmodium falciparum (Pf) DXR enzyme and its known inhibitor, fosmidomycin. Positive STD-NMR and in silico docking data obtained for some of the compounds indicate their capacity
