Organocatalytic Asymmetric Triple Domino Reactions of Nitromethane with α,β-Unsaturated Aldehydes
Publication History
Publication Date:
08 October 2009 (online)
Abstract
An organocatalytic asymmetric multicomponent domino reaction employing the bulk chemical nitromethane and α,β-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.

General Procedure
In
an ordinary vial equipped with a magnetic stirring bar, the α,β-unsaturated
aldehyde 1 (2.2 mmol, 2.2 equiv) was dissolved
in CHCl3 (1 mL). The catalyst (S)-2 (0.2 mmol, 0.2 equiv) and nitromethane
(1 mmol, 1 equiv) were added to the solution. The vial was sealed,
and the mixture was stirred for 20 h at r.t. The crude reaction
mixture was diluted in CH2Cl2, washed with
H2O, and dried over MgSO4. After concentration,
the crude product was purified by flash chromatography (silica gel,
pentane-EtOAc). All new compounds gave satisfactory spectroscopic
and analytical data. As a typical example, the data of the compound 3a are given.
