Stereoselective Multiple Bond-Forming Transformations (MBFTs): The Power of 1,2-and 1,3-Dicarbonyl Compounds

Although long known, 1,2- and 1,3-dicarbonyl compounds have recently come more and more to prevalence as ideal substrates for the invention of new stereoselective multiple bond-forming transformations (MBFTs). Herein, a critical appraisal is presented of some of the most spectacular of these MBFTs, which allow the formation from three up to six bonds in highly step- and atom-economical processes.
