• Copper(I)-Catalyzed 3-Position Methylation of Coumarins by Using Di-<i>tert</i>-butyl Peroxide as the Methylation Reagents
  作者：Huan Zhuang、Runsheng Zeng、Jianping Zou

  DOI：10.1002/cjoc.201500836

  日期：2016.4

  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.
