Shi, Min published the artcileCatalytic, asymmetric aza-Baylis-Hillman reaction of N-sulfonated imines with 2-cyclohexen-1-one and 2-cyclopenten-1-one in the presence of a chiral phosphine Lewis base, Related Products of esters-buliding-blocks, the publication is Tetrahedron: Asymmetry (2005), 16(7), 1385-1391, database is CAplus.
In the aza-Baylis-Hillman reaction of N-sulfonated imines with 2-cyclohexen-1-one or 2-cyclopenten-1-one the Baylis-Hillman adducts can be obtained in good yields and moderate enantiomeric excess. by using (R)-2′-dimethylphosphanyl-[1,1′]binaphthalenyl-2-ol as a chiral phosphine Lewis base.,. The structure of this chiral phosphine Lewis base on chiral induction in this reaction has also been discussed.
