The reaction of Hagemann’s ester andan electrophile can occur theoretically at C-1, C-3, C-5, andC-2’ positions (Fig. 1). As an example, however, it has beengenerally accepted that the site preference for alkylation wasC-3, the resulting C-3-alkyl derivatives often being accom-panied by small amounts of the C-1-alkyl products.
哈格曼酯和亲电试剂的反应理论上可以发生在 C-1、C-3、C-5 和 C-2' 位置(图 1)。然而,作为一个例子,已普遍接受烷基化的位点偏好是C-3,得到的C-3-烷基衍生物通常伴随有少量的C-1-烷基产物。
