benzyl thioethers has been delineated through base-induced ring transformation of 6-aryl-4-methylthio-2H-pyran-2-one-3-carbonitriles, methyl 6-aryl-4-methylthio-2H-pyran-2-one-3-carboxylates and 6-aryl-4-(piperidin-1-yl)-2H-pyran-2-one-3-carbonitriles by either 1-phenoxypropan-2-one, 1,3-diphenoxypropan-2-one or 4-arylthiobutan-2-one, under very mild reaction conditions, in excellent yield.
通过碱诱导的 6-芳基-4-甲硫基-2H-吡喃-2-one-3-腈、甲基6-芳基-4-环转化,描述了二芳基醚和芳基苄基硫醚的高效一锅合成甲硫基-2H-吡喃-2-one-3-carboxylates 和 6-aryl-4-(piperidin-1-yl)-2H-pyran-2-one-3-carbonitriles 由 1-phenoxypropan-2-one, 1 ,3-diphenoxypropan-2-one 或 4-arylthiobutan-2-one,在非常温和的反应条件下,以优异的收率。
