Abstract

Michael-type hydroaminations of acrylonitrile, phenyl vinyl sulfone, and dimethyl maleate were realized using arylamines catalyzed independently by Yb(OTf)3 and Tb(OTf)3 to give the desired β-aminonitriles, β-amino sulfones, and dimethyl aspartates, respectively, in moderate to excellent yields. The reactions were carried out in toluene for Yb(OTf)3 and in t-BuOMe for Tb(OTf)3, all reactions were performed at 100 °C.
