通过锂化丙二烯1的氧化偶联，以几种立体异构形式形成标题化合物2。其中一个在同旋闭环中快速环化得到3，另一个缓慢环化得到4，其通过X射线结构分析表征。芳基= 2，4，6-tBu 3 C 6 H 2。
By oxidative coupling of the lithiated allene 1, the title compound 2 is formed in several stereoisomeric forms. One of them cyclizes rapidly in a conrotatory ring closure to give 3, another cyclizes slowly to give 4, which was characterized by an X‐ray structure analysis. Aryl= 2, 4, 6‐tBu 3 C 6 H 2.
