CAN promoted oxidative cyclization of dimethyl 4-pentenylmalonate has been investigated in MeOH and in AcOH. The product distribution and the regioselectivity of the reaction (5-exo/6-endo ratio) appear to be very sensitive to the reaction conditions as well as the presence and the nature of copper salts, which can also be exploited from the synthetic point of view.
已经在MeOH和AcOH中研究了CAN促进4-戊烯基丙二酸二甲酯的氧化环化作用。反应的产物分布和区域选择性(5-exo / 6-endo比率)似乎对反应条件以及铜盐的存在和性质非常敏感,这也可以从合成的角度加以利用。看法。
