A chiral β-diketone Cu(II) catalyst Cu(dcm)2 was synthesized and used for the asymmetric cyclization of α-diazoketones, and high chemical yields and good enantioselectivity of products were achieved. The effect of the structure of substrate on the enantioselectivity was studied.

Key words: chiral catalyst, α-diazoketone, cyclization
