英文摘要	as a versatile intermediate, chiral alpha-cyanohydrins can be synthesized by asymmetric trimethylsilylcyanation of aldehydes. schiff base-ti complexes have been proven to be excellent catalysts for this reaction. polysalen-ti (iv) complex was successfully used in asymmetric trimethylsilylcyanation of benzaldehyde and its substitutes. the adducts of trimethylsilylcyanation of 4-ch3-c6h4cho and 4-cl-c6h4cho were obtained with ee = 82 %, yield = 93 %, and ee = 82 %, yield = 98 %, respectively, at -40 degreesc. the catalyst could be recycled for 5 times while maitaining its activity and enantioselectivity at 20 degreesc.
