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*=C5 Me5 ).
开发了一种新型的氧化导向基团,用于铑(III)催化的 N-苯氧乙酰酰胺与炔烃的 CH 官能化反应。反应条件的微小变化导致邻羟苯基取代的烯酰胺或环化以高选择性得到苯并呋喃(见方案;Cp*=C5 Me5 )。
