An unprecedented tandem oxidation/Michael/aldol reaction is reported. The diastereoselective formation of only a single isomer of dispirocyclopentanebisoxindole and dispiro[acenaphthylene-1,1′-cyclopentane-3′,1′′-acenaphthylene]-2,2′′dione is presented. The reaction generates two new C–C bonds and two all-carbon quaternary chiral stereocenters in a single step.
据报道,史无前例的串联氧化/迈克尔/羟醛反应。提出了双螺环戊烷双恶吲哚和双螺环[ac-1,1'-环戊烷-3',1''-ac] -2,2''二酮的单一异构体的非对映选择性形成。该反应可在一个步骤中生成两个新的C–C键和两个全碳四元手性立体中心。
