Syntheses of new sulfinylcinnolines, quinoxalines, quinazolines and phtalazines have been investigated starting from the appropriate halogenobenzodiazine derivatives. The latter were converted in one step to the corresponding sulfanyl benzodiazines which upon oxidation with m-CPBA led to the corresponding sulfoxide derivatives of benzodiazines in moderate to good yields. In parallel to this study,
从合适的卤代苯并二嗪衍生物开始,已经研究了新的亚磺酰基cinnolines,喹喔啉,喹唑啉和酞嗪的合成。后者转化在一个步骤中,以相应的硫烷基benzodiazines其在用氧化米-CPBA导致benzodiazines的相应的亚砜衍生物在中度至良好的产率。与这项研究同时进行的是,还描述了一种从2-硫烷基喹喔啉开始合成2-甲基亚磺酰基喹喔啉的改进方法,在喹唑啉系列中,已经开发了一种合成方法来制备2-叔丁基-5-苯基亚磺酰基喹唑啉,其收率令人满意。以及2-叔丁基-5-叔丁基亚磺酰基-4(3 H)-喹唑啉酮和2-叔丁基-8-叔丁基亚磺酰基-4(3 H)-喹唑啉酮。
