Problems solved by technology

It has become one of the hot spots of research at home and abroad, and there have been a large number of reports in the literature. -Crafts) condensation reaction, Aldol (aldol) condensation reaction and many other reactions show good asymmetric catalytic activity and high enantioselectivity However, due to the limitations of the catalyst itself, for example, the catalyst is unstable in air , the amount of catalyst used is too large, the reaction is carried out at low temperature and other shortcomings, it is difficult to realize industrialization
