The title compound 1b reacts with cyclopentadiene to give a single cycloadduct, assigned the stereostructure 6a by X-ray crystallography; single cycloadducts, i.e.4c and d, also arise in the corresponding reactions involving the dienes 2b and c.
标题化合物1b与环戊二烯反应得到单一环加合物,通过X射线晶体学将其立体结构指定为6a;单一环加合物,即 4c 和 d,也在涉及二烯 2b 和 c 的相应反应中产生。
