Highly enantioselective addition of 1-fluoro-1-nitro(phenylsulfonyl)methane to α,β-unsaturated aldehydes
Highly enantioselective addition of 1-fluoro-1-nitro(phenylsulfonyl)methane to α,β-unsaturated aldehydes
An organocatalytic, highly enantioselective addition of 1-fluoro-1-nitro(phenylsulfonyl)methane to α,β-unsaturated aldehydes is reported. The reaction is simply catalyzed by secondary amines and furnishes the corresponding fluorinated derivatives in good yields, with moderate diastereoselectivities and excellent enantioselectivities. The absolute configuration of the major diastereomers was unambiguously ascertained by X-ray diffraction analysis.

Abstract
An organocatalytic, highly enantioselective addition of 1-fluoro-1-nitro(phenylsulfonyl)methane to α,β-unsaturated aldehydes is reported. The reaction is simply catalyzed by secondary amines and furnishes the corresponding fluorinated derivatives in good yields, with moderate diastereoselectivities and excellent enantioselectivities. The absolute configuration of the major diastereomers was unambiguously ascertained by X-ray diffraction analysis.
