decarboxylative aldol reaction between malonic acid half-oxyesters and various carbonyls with carboxylate assistance was developed, affording structurally diverse β-hydroxy esters with good yields and enantioselectivities under mild conditions. Importantly, the broad substrate scope of this methodology enabled rapid accesses to several natural products and their analogues as exemplified by phenylpropanoid, phaitanthrin
建立了Ni-恶唑啉配合物催化丙二酸半含氧酸酯和各种羰基在羧酸酯辅助下的不对称脱羧醛醇缩合反应,在温和条件下以良好的收率和对映选择性提供了结构多样的β-羟基酯。重要的是,这种方法的广泛的底物范围使人们能够快速获得几种天然产物及其类似物,例如苯丙烷,类赤霉素B和邻苯二甲酸酯。
