developed a simple and an efficient route to a range of angularly fused spirocycles by the application of enyne metathesis and the Diels–Alder reaction as key steps. The enyne metathesis protocol has been further extended to the dibenzylation of indane-1,3-dione by using cross-enyne metathesis in the presence of hexa-1,5-diene with the aid of Grubbs’ 1st generation catalyst followed by an aromatization
摘要 通过应用烯炔复分解和Diels-Alder反应作为关键步骤,我们已经开发出了一种简单而有效的途径,可用于一系列有角度融合的螺环。借助Grubbs的第一代催化剂,在hexa-1,5-diene存在下使用交叉烯炔复分解,将烯炔复分解方案进一步扩展至茚满1,3-二酮的二苄基化反应。与DDQ。 通过应用烯炔复分解和Diels-Alder反应作为关键步骤,我们已经开发出了一种简单而有效的途径,可用于一系列有角度融合的螺环。借助Grubbs的第一代催化剂,在hexa-1,5-diene存在下使用交叉烯炔复分解,将烯炔复分解方案进一步扩展至茚满1,3-二酮的二苄基化反应。与DDQ。
