在5 mol % Cr(III)-salen络合物1的存在下,宽范围的取代的1-氨基-1,3-丁二烯与甲基丙烯醛进行对映选择性Diels-Alder反应。该反应在室温下方便地进行,并且它们以高产率和优异的ee's提供环加合物。
[GRAPHICS]A broad range of substituted 1-amino-1,3-butadienes undergo enantloselective Diels-Alder reactions with methacrolein in the presence of 5 mol % of Cr(III)-salen complex 1. The reactions are carried out conveniently, at room temperature, and they afford the cycloadducts in high yields and excellent ee's.
