efficient procedure for synthesizing oxazines was developed by the palladium(0)-catalyzed intramolecular cyclization of a benzamide through a π-allylpalladium (II) complex. Interestingly, the diastereoselectivity of oxazine ring formation was dominantly controlled by the bulkiness of various protecting groups on the secondary alcohols.
通过钯(0)催化苯酰胺通过π-烯丙基钯(II)配合物的分子内环化,开发了一种有效的合成恶嗪的方法。有趣的是,恶嗪环形成的非对映选择性主要受仲醇上各种保护基团的体积控制。
