摘要：

The development of a Ni(II) (S)-Tol-BINAP-catalyzed enantioselective alkylation of N-acylthiazolidinethiones with trimethyl orthoformate is described. The reaction is general with respect to the thiazolidinethione, providing the desired adducts in good to excellent yield and with high levels of enantioselectivity (11 examples, 51-92% yield, 90-99% ee). The products are readily converted into a variety of synthetically useful derivatives in a straightforward manner. Copyright © 2005 American Chemical Society.
