be considered as a new frontier in the development of stereoselective reactions. An organocatalytic procedure mediated by the MacMillan imidazolidinone catalyst was coupled with an InBr3‐mediated process for the development of a novel stereoselective allylation reaction of aldehydes. Up to 98 % ee and up to 5:1 d.r. were obtained in the process.
acetates and sodiodimethylmalonate proceeds in high yields and enantioselectivities (up to 99% ee) using a diphenylphosphinoaryl oxazoline ligand. The so-formed substitution products are transformed into enantiomerically enriched succinicacids and also into enantiomerically enriched γ-lactones.
