摘要

enaminone 3 (213 mg, 90% yield) as a colorless liquid.'Some examples of the reaction are summarized in Table I. This method is applicable to a variety of enol silyl ethers and ketoxime sulfonates. Of all the Lewis acids examined diethylaluminum chloride and ethylaluminum dichloride (2-3 equiv) have proven to be the most efficacious, and other Lewis acids (AlCl,, SnCl,, FeCl,, TiC14, Me, SiOTf, Me, SiI, etc.) gave less satisfactory ...
