以1-苯基-1-丙炔为模型炔,将高烯丙基频哪醇硼酸酯应用于钴催化的桤木烯反应中,生成含烯丙基硼酸酯亚基的桤木烯中间体。这些中间体在烯丙基硼化反应中与醛原位转化。烯丙基硼化反应的非对映选择性通过桤木烯反应来控制,该反应主要产生E-构型的烯丙基硼酸酯亚基,从而产生顺烯丙基硼化产物。
A homoallylpinacolboronic ester has been applied in cobalt-catalyzed Alder ene reactions with 1-phenyl-1-propyne as the model alkyne to generate Alder ene intermediates with an allyl-boronate subunit. These intermediates are converted in situ with aldehydes in an allylboration reaction. The diastereoselectivity of the allylboration reaction is controlled via the Alder ene reaction, which generates theE-configured allylboronate subunit predominantly, thereby leading to thesyn-allylboration product.
