In the presence of a neutral dppf-modified iridium catalyst and Cs2CO3, linear allylic acetates react with primary amines to form products of hydroamination with complete 1,3-regioselectivity. The collective data, including deuterium labeling studies, corroborate a catalytic mechanism involving rapid, reversible acetate-directed aminoiridation with inner-sphere/outer-sphere crossover followed by turnover-limiting
Polymer-supported silyl enol ethers (thioketene silyl acetals) were prepared from chloromethyl copoly-(styrene-1%-divinylbenzene) resin. The silyl enol ethers reacted with imines in the presence of a catalytic amount of scandium triflate (Sc(OTf)3) to afford β-amino thioesters, which were reduced to amino alcohols in good yields. These reactions provide a convenient method for the preparation of an
