Via C-2 and C-6 hydroxyl group of β-cyclodextrin(CD) were functionally modified respectively,the AB2 type β-CD functional monomer with Si-H and double bonds was synthesized by hydrosilylation and Michael addition reaction,and the molecular structure of the functional monomer was characterized with 1H NMR,MALDI-TOF MS and element analysis.

Recent developments in organozinc reagents on asymmetric addition catalyzed by sul- fur-containing chiral ligands are reviewed according to the type and number of the coordinating atoms.

The recent advancement of the asymmetric addition of organozinc reagents to ketones and α-ketoesters is reviewed according to the type of the chiral ligands, with an emphasis on the introduction of the ligands with high efficiency and high selectivity.

The optically pure compounds (5R,4R)-5-(l-menthyloxy)-4-dialkyloxyphosphonyl-butyrolactones were obtained by using asymmetric Michael addition reaction of 5(R)-5(l-menthyloxy)-2(5H)-furanone with nucleophilic trialkylphosphite.

In the study of the asymmetric Michael addition reaction of cyclohexanone toβ-nitrostyrene, it was found that homo-diphenylprolinol methyl ether catalyst 62a was capable of promoting the reaction with the good result.

It was found that the best catalyst was the 4-trifluoromethanesulfonamidyl prolinol tert-butyldiphenylsilyl ether 57a when these bifunctional organocatalysts were used to catalyze the asymmetric Michael addition reaction of cyclohexanone toβ-nitrostyrene.
