Yb(OTf)3 catalyzed mild and regioselective ring-opening 1,3-aminothiolation of donor-acceptor (D-A) cyclopropanes using sulfenamides has been demonstrated. The insertion of the C-C σ-bond of D-A cyclopropanes into the S-N σ-bond of sulfenamides allows the synthesis of diverse γ-aminated α-thiolated malonic diesters in moderate to good yields (up to 87%) with good functional group compatibility. The stereospecificity of the reaction was demonstrated using enantiomerically pure D-A cyclopropane.
