ABSTRACT An efficient protocol for the Lewis acid catalyzed three-component aza-Diels-Alder reaction of pentafulvenes as dienophile has been developed. Cyclopentene fused tetrahydroquinolines were formed in good yields with excellent diastereoselectivities. The method was extended to spiro[2,4]hepta-4,6-diene, by which 3,4-dihydroquinoline derivatives were obtained. The aromatization of cycloadducts
摘要 已经开发了一种用于路易斯酸催化的五富烯作为亲二烯体的三组分氮杂-狄尔斯-阿尔德反应的有效方案。环戊烯稠合的四氢喹啉以良好的收率和优异的非对映选择性形成。该方法扩展到螺[2,4]庚-4,6-二烯,由此获得3,4-二氢喹啉衍生物。环加合物的芳构化提供相应的喹啉衍生物。图形概要
