carrying a halogen and an amino- or hydroxy group have been converted to allylamino- or allyloxy-furyl-(hetero)arenes. These compounds underwent IMDAF reactions to give complex fused polycyclic heterocycles. The reactivity of the substrates was highly dependent on the detailed substitution pattern, however cyclizations occurred with high stereoselectivity in most cases. Experimental findings regarding
带有卤素和氨基或羟基的芳烃和杂芳烃已被转化为烯丙基氨基-或烯丙氧基-呋喃基-(杂)芳烃。这些化合物进行IMDAF反应,得到复杂的稠合多环杂环。底物的反应性高度依赖于详细的取代模式,但是在大多数情况下,环化反应以高立体选择性发生。计算支持了有关反应性和立体选择性的实验发现。
