The copper‐catalyzed methylation of coumarin by using di‐tert‐butyl peroxide (DTBP) has been described. The reaction provides direct access to a wide range of 3‐methylcoumarins in moderate to good yields. In this procedure, it is noteworthy that DTBP was employed not only as the oxidant, but also as the methyl source.
已经描述了使用二叔丁基过氧化物(DTBP)铜催化香豆素的甲基化。该反应可以以中等到良好的产率直接获得各种3-甲基香豆素。在该程序中,值得注意的是,DTBP不仅用作氧化剂,而且用作甲基源。
