Abstract

An enantioselective synthesis of substituted 2-aminotetralins from dihydronaphthalenes in four steps is described. The key step is the Jacobsen's (diimine) copper-catalyzed asymmetric aziridination of dihydronaphthalenes to the respective aziridines in 33–82% yields and 60–87% enantiomeric excess. The enantioselectivity and the yield were dependent on the properties of the nitrene precursor. pTsNIPh appeared in general to ...
