One pot selective syn diacetoxylation of in situ generated cinnamic esters using PhI(OAc)₂/T3P system, started from gem‑dibromomethylarenes in the presence malonoate esters/malononitrile. A broad range of substrates including both electron-deficient and electron-donating gem‑dibromomethylarenes could be efficiently elaborated by this developed methodology thereby furnishing the desired products in good to excellent yields.

对于非对映选择性一锅串联的方法合成肉桂酸酯的-diacetoxylation

一锅选择性合成的diacetoxylation使用岛（OAC）原位产生的肉桂酸酯₂ / T3P系统中，从开始宝石-dibromomethylarenes在存在malonoate酯/丙二腈。通过这种开发的方法可以有效地加工包括缺电子和供电子的宝石二溴甲基芳烃在内的广泛的底物，从而以良好到出色的产率提供所需的产品。
