摘要

Allyltrimethylsilane and CAN. We treated a methanol solution containing a 1, 3-diketone (ie, 10 and 12) and allyltrimethylsilane (5, 1.3 equiv) in methanol with CAN (2.1 equiv). After I 1 min at room temperature, the solution turned from dark brown to pale yellow or colorless. Change of the color indicated completion of the reactions. Workup followed by purification afforded the allylated product &e., 11 and 13) in excellent yields (91-98%; entries 2 and 3 ...
