Recommanded Product: Chalcone. The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.
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).
Recommanded Product: Chalcone. About Chalcone, If you have any questions, you can contact Jiang, ZW; Toffano, M; Vo-Thanh, G; Bournaud, C or concate me.
