Coupling of α-chloro enamines as key building blocks with alkenyl lithium compounds lead to the formation of 2-amino-1,3-dienes 6. These cross conjugated enamines constitute important diene components for stereoselective Diels-Alder reactions and were prepared in 32–75% overall yield starting from the corresponding amides.
α-氯烯胺作为主要的结构单元与烯基锂化合物的偶联导致形成2-氨基-1,3-二烯6。这些交叉共轭的烯胺构成了立体选择性Diels-Alder反应的重要二烯成分,从相应的酰胺开始,总产率为32-75%。
