excellent nucleophiles in Pd-catalyzed allylic alkylation. The method allows for the stereoselective introduction of a wide range of side chains, including highly functionalized ones. Both diastereomers can be accessed through variation of the reaction conditions. Furthermore, the use of stannylated carbonates introduces vinylstannane motifs, which are eligible for subsequent C–C coupling reactions.
N-(α-羟基酰基)-甘氨酸酯可以用作Pd催化的烯丙基烷基化反应中的优良亲核试剂。该方法允许立体选择引入各种侧链,包括高度官能化的侧链。两种非对映异构体均可通过改变反应条件来获得。此外,使用甲锡烷基化碳酸酯会引入乙烯基锡烷基序,这些基序可用于后续的C–C偶联反应。
