The enantioselective synthesis of carbocyclic nucleosides through the palladium‐catalyzed asymmetric allylic amination of alicyclic Morita‐Baylis‐Hillman (MBH) adducts with purines was successfully developed. With a combination of Pd 2 (dba) 3 / L7 as catalyst, various optically active carbocyclic nucleosides featuring a C=C double bond in the carbocycle moiety were obtained in high yields (up to 97%) with excellent N 9 /N 7 ‐selectivities (>95/5) and enantioselectivities (up to >99.6%). In addition, these nucleoside analogs allowed for rapid transformation to a variety of other interesting structurally diverse chiral carbocyclic nucleosides.
