摘要:
An organocatalytic asymmetric multicomponent domino reaction employing the bulk chemical nitromethane and alpha,beta-unsaturated aldehydes as substrates is described. The new triple cascade reaction based on two subsequent Michael additions and an intramolecular aldol condensation provides an atom-economic entry to diastereo- and enantiomerically pure 5-nitrocyclohexene carbaldehydes after flash chromatography.
