The first collectively asymmetric total synthesis of all members of lycorane, including (+)-α, (+)-β, (+)-γ, and (−)-δ, in a catalytic manner has been achieved. The cornerstone of this synthesis features an asymmetric, stereodivergent Ir/amine dual catalytic α-allylation of 2-phthalimidoacetaldehyde.
已经实现了第一次以催化方式对所有成员的 lycorane 进行集体不对称全合成,包括 (+)-α、(+)-β、(+)-γ 和 (-)-δ。该合成的基石具有不对称、立体发散的 Ir/胺双催化 α-烯丙基化 2-邻苯二甲酰亚胺基乙醛。
