2-Hydroxy-4-morpholin-2,5-diarylfuran-3(2H)-one derivatives were constructed sequentially using iodine and zinc dust from simple and readily available methyl ketone and morpholine as the starting materials. Under mild conditions, C–C, C–N, and C–O bonds formed in a one-pot synthesis. A quaternary carbon center was successfully constructed, and the active drug fragment morpholine was introduced into the molecule
以简单易得的甲基酮和吗啉为原料,使用碘和锌粉依次构建了2-羟基-4-吗啉-2,5-二芳基呋喃-3(2H ) -酮衍生物。在温和条件下,C-C、C-N 和 C-O 键在一锅合成中形成。成功构建了季碳中心,并将活性药物片段吗啉引入到分子中。
