An efficient and flexible synthesis of a new class of chiral bifunctional NHC catalyst has been reported. These new imidazolylidene NHCs, bearing a (thio)urea function as a hydrogen bond donor promoted efficiently highly diastereoselective trans-cyclopentannulation of enals and enones in moderate to good yields (up to 69 % yield) along with excellent enantioselectivity (up to 96 % ee). This methodology could be applied to a large variety of substrates (30 examples).
Formula: C15H12O. Bye, fridends, I hope you can learn more about C15H12O, If you have any questions, you can browse other blog as well. See you lster.
