Vinylic oxetanes react in an SN2′ manner with a variety of potential nucleophiles in the presence of catalytic amounts of Pd(PPh3)4 to afford the corresponding highly functionalized, di- and trisubstituted homoallylic alcohols with high stereoselectivity.
在催化量的Pd(PPh 3)4存在下,乙烯基氧杂环丁烷以S N 2'的方式与多种潜在的亲核试剂反应,从而提供具有高立体选择性的相应的高度官能化的二取代和三取代的均烯丙基醇。

Diastereoselective Iodocarbocyclization Reaction of 2- or 3-Oxy-4-pentenylmalonate Derivatives
induction in the iodocarbocyclizationreaction of 4-pentenylmalonate derivatives having a stereogenic center at an allylic or a homoallylic position has been investigated. The iodocarbocyclizationreactions of 3-oxy-4-pentenylmalonate derivatives proceeded with high cis-selectivity through stereoelectronic control of the oxygenated substituent at an allylic position. In the reaction of (S)-2-siloxy-4-pentenylmalonate
