[GRAPHICS]A flexible approach to functionalized and enantioenriched aziridines has been developed from an intermediate aziridinylmethyl tosylate. This protocol features a Cu-catalyzed Grignard substitution reaction that allows a range of functionalized organic fragments to be incorporated. Moreover, a convenient one-pot procedure is outlined that allows the trityl group to be exchanged for a range of common N-protecting groups.
An Enantiospecific Approach to Triazolylalanine Derivatives
enantiomerically pure aziridinylmethyl azide is described that can be transformed to the corresponding triazole by a copper-catalysed [3+2] alkyne cycloaddition reaction. The transformation of these intermediates into triazolylalanine-type derivatives by aziridine ring-opening reactions is also described. copper catalyst - 1,2,3-triazole - aziridine - cycloaddition - ring-opening reaction - alanine
