Give it a tweak: A novel oxidizing directing group was developed for a rhodium(III)‐catalyzed CH functionalization of N‐phenoxyacetamides with alkynes. A small change in the reaction conditions leads to either ortho‐hydroxyphenyl‐substituted enamides or cyclization to deliver benzofurans with high selectivity (see scheme; Cp*=C5Me5).
给它一个调整:一种新颖的氧化定向基团被用于铑(III)催化的开发Ç h的官能Ñ与炔-phenoxyacetamides。反应条件的微小变化会导致邻-羟苯基取代的酰胺或环化反应以高选择性提供苯并呋喃(参见方案; Cp * = C 5 Me 5)。
