Herein, an efficient (tBuO)2Mg promoted [3 + 2] annulation of δ-acetoxy allenoates with N-benzylhydroxylamine has been developed. This method provides a concise and facile protocol to synthesize vinylated isoxazol-5(2H)-one derivatives stereospecifically in a broad substrate scope with high efficiency (31 examples, up to 87% yield).
在此,开发了一种有效的 ( t BuO) 2 Mg 促进 δ-乙酰氧基联烯酸酯与N-苄基羟胺的 [3 + 2] 环化。该方法提供了一种简洁、简便的方案,可在广泛的底物范围内高效地立体定向合成乙烯基化异恶唑-5(2 H )-酮衍生物(31 个实例,产率高达 87%)。
