underwent this transformation in high yield and ee, and products can be readily transformed into γ-allyl enals via a Cope rearrangement without erosion of ee. This transformation was used to install the quaternary stereocenter in (S)-bakuchiol, enabling completion of a concise formal synthesis.
报道了 enals 的催化对映选择性去共轭烯丙基化。多种烯醛在高产率和ee上经历了这种转变,并且产物可以通过Cope重排容易地转化为γ-烯丙基烯醛,而不会侵蚀ee。该转换用于在 ( S )-补骨脂酚中安装四元立体中心,从而能够完成简明的正式合成。
