Chiral allylrhodium nucleophiles: The highly diastereo‐ and enantioselective title reaction of a range of cyclic imines with various potassium allyltrifluoroborates most likely proceeds via allylrhodium(I) intermediates, and represents the first rhodium‐catalyzedenantioselective nucleophilic allylation of π electrophiles with allylboron compounds.

position of the boron atom. Representative examples of manipulation of the products are also described. This article presents further examples of the enantioselective rhodium-catalyzed addition of potassium allyltrifluoroborates to cyclicimines. A wide range of substituted allyl-trifluoroborates are compatible with this process, and provide protected homoallylic amines with high levels of diastereo- and
