A new stereocontrolled route to (−)-kainic acid, the representative of the kainoid amino acids and exhibiting insecticidal, anthelmintic and neuroexcitatory properties, has been devised in an enantioconvergent way using either (+)- or (−)-ketodicyclopentadiene as the starting material by employing a concurrent retro-Diels-Alder reaction and intramolecular ene reaction as the key step.
以(+)-或(-)-酮二环戊二烯为起始剂,以对映体会聚的方式设计了一种新的立体控制的途径,该途径以(2-)-海藻酸为代表,是一种以类胡萝卜素为代表的氨基酸,并具有杀虫,驱虫和神经兴奋特性。通过同时进行逆Diels-Alder反应和分子内烯键反应是关键步骤。
