synthesized an advanced synthetic intermediate, hydroxy lactam 3, which has previously been converted to perhydrohistrionicotoxin. An important feature of this synthesis is the creation of stereogenic centers by using the cyclic amino acid ester−enolate Claisen rearrangement together with a ring-closing metathesis for azaspirocyclic skeleton construction.
我们已经成功地合成了一种先进的合成中间体,羟基内酰胺3,以前已被转化为过氢组氨酸毒素。该合成的重要特征是通过使用环状氨基酸酯-烯醇式克莱森重排以及闭环易位以形成氮杂螺环骨架,来建立立体异构中心。
