Regio- and stereo-controlled opening of 2,3-epoxy amines and 2,3-aziridine amines by the commercially available MgBr2 is described. As reported, this new method could represent a general and useful approach for the preparation of promising intermediates. Moreover, in particular cases, the reaction evolves toward an interesting oxazolidin-2-one structure. J. Heterocyclic Chem., (2010).
highly efficient stereoselectivesynthesis of (1R,2R)-phenyl-2-decanoylamino-3-morpholinopropan-1-ol (d-threo-PDMP) is described. The approach, based on the ring expansion of the aziridine ring to oxazoline, could be applicable to the synthesis of many analogues with different amide chains and sugar mimic portions. regioselectivity - ringopening - glycosidases - inhibitors - ring expansion
