Smooth salen: Ru(CO)-salen complex 1 is an effective catalyst for asymmetric benzylic and allylic C-H bond amination using 2-(trimethylsilyl) ethanesulfonyl azide (SESN3) as the nitrene source. The reaction proceeded with high enantioselectivity and excellent regioselectivity. An ethyl group can be selectively aminated, even in the presence of an n-propyl group. No migration or isomerization of the double bond was observed.
