杂环化合物是最大的一类具有重要医药、化学和工业应用的有机化合物。在这里,我们报告的发现和发展的可见光诱导,协同激发态铜催化使用的组合Cu(IPr)I作为催化剂和rac-BINAP作为配体,产生超过10个不同类别的杂环。该反应耐受广泛的官能团和复杂的分子支架,包括肽衍生物、天然产物和市售药物。初步的机理研究表明,在原位生成的[Cu(BINAP)2]+和[Cu(IPr)2]+催化剂,在可见光照射下协同工作,以促进未活化的烯烃的催化carbo-aroylation,提供了广泛的有用的杂环。可见光诱导的激发态铜催化能够合成超过10种不同类别的杂环。该反应耐受广泛的官能团和复杂的分子支架,包括肽衍生物、天然产物和市售药物。
Heterocycles represent one of the largest groups of organic moieties with significant medicinal, chemical, and industrial applications. Herein, we report the discovery and development of visible-light-induced, synergistic excited-state copper catalysis using a combination of Cu(IPr)I as a catalyst and rac-BINAP as a ligand, which produces more than 10 distinct classes of heterocycles. The reaction tolerates a broad array of functional groups and complex molecular scaffolds, including derivatives of peptides, natural products, and marketed drugs. Preliminary mechanistic investigation suggests in situ generations of [Cu(BINAP)2]+ and [Cu(IPr)2]+ catalysts that work cooperatively under visible-light irradiation to facilitate catalytic carbo-aroylation of unactivated alkenes, affording a wide range of useful heterocycles. Visible-light-induced excited-state copper catalysis enables the synthesis of more than 10 distinct classes of heterocycles. The reaction tolerates a broad array of functional groups and complex molecular scaffolds, including derivatives of peptides, natural products, and marketed drugs.
