Xiao, Wei published the artcileOrganocatalytic Asymmetric Four-Component [5+1+1+1] Cycloadditions via a Quintuple Cascade Process, COA of Formula: C9H7NO2, the publication is Advanced Synthesis & Catalysis (2018), 360(18), 3526-3533, database is CAplus.
An asym. four-component [5+1+1+1] formal cycloaddition reaction of 3-substituted 2-cyclopentenones, activated methylene nucleophiles and two mols. of aldehydes was developed under chiral primary aminocatalysis, producing a diversity of highly enantioenriched fused and spirocyclic frameworks with high mol. complexity. Mechanism studies indicated that the current reaction proceeded in a challenging cascade quintuple Knoevenagel condensation/Michael addition/retro-Michael addition/Michael addition/Michael addition sequence via diverse aminocatalytic modes.
