Chelated enolates are versatile nucleophiles for palladium-catalysed allylic alkylations. Even with complex allylic substrates the reaction proceed without significant isomerisation. This allows the stereoselective introduction of polyhydroxylated allylic sidechains into amino acids and peptides with retention of the olefin geometry.
螯合的烯醇盐是用于钯催化的烯丙基烷基化反应的通用亲核试剂。即使使用复杂的烯丙基底物,反应也可以进行,而无需明显的异构化。这允许将多羟基化的烯丙基侧链立体选择性地引入氨基酸和肽中,并保留了烯烃的几何形状。
