A large number of chemical researchers are favored of the methodology and application of the asymmetric synthesis especially catalyzed by organocatalisis. At the same time, organocatalisis have played an important role in the fields of the synthesis and most of the reactions which were catalytyzed by organocatalisis can get much higher yield and good stereoselectivity.
Proline is the most successful and widespread using of the organocatalysis but in some areas there are still shortcomings. Thus, a vari...
