regioselective, and convergent method for the ring expansion and rearrangement of 1‐sulfonyl‐1,2,3‐triazoles under rhodium(II)‐catalyzed conditions is described. These denitrogenative reactions form substituted enaminone and olefin‐based products (see scheme). The enaminone products can be further functionalized to give various heterocycles and ketone derivatives, thus rendering the sulfonyl triazole traceless
扩展空间:描述了一种在铑 (II) 催化条件下进行 1-磺酰基-1,2,3-三唑环扩展和重排的有效、区域选择性和收敛方法。这些脱氮反应形成取代的烯胺酮和基于烯烃的产物(参见方案)。烯胺酮产物可以进一步官能化,得到各种杂环和酮衍生物,从而使磺酰三唑变得无痕。
