摘要：

Dilithium 2,2'-methylenebis(4,6-di-tert-butylphenoxide) can be successfully utilized as a bidentate Lewis acid for simultaneous coordination to carbonyl groups, thereby accelerating the Diels-Alder reactions. The double activation ability of the bidentate lithium reagent toward carbonyls is emphasized in comparison with the corresponding monodentate lithium reagent. (C) 1998 Elsevier Science Ltd.
