chloride, has been demonstrated. Several activated alkenes produce functionalized 1,7-octadiene derivatives in one pot. The additions of substituted allyl acetates are highly regioselective. The Grubbs cyclization of octadiene derivatives gives an easy access to stereodefined substituted cyclohexene derivatives.
一种有效的邻位活化烯烃的烯丙基乙酸酯和双allylstannanes由烯丙基化的纳米颗粒的钯催化,产生原位从钯(II),氯化,已得到证明。几种活化的烯烃在一罐中产生官能化的1,7-辛二烯衍生物。取代的乙酸烯丙酯的添加是高度区域选择性的。辛二烯衍生物的Grubbs环化可轻松获得立体定义的取代的环己烯衍生物。
