Abstract
The first asymmetric catalytic aldol-cyclization reaction of detrifluoroacetylatively in situ generated enolates with methyl 2-formylbenzoate is reported. This reaction tolerates a wide range of substrates, affording fluorinated quaternary stereogenic α,α-dialkyl/cyclo-alkyl-β-ketoesters with good yields, high diastereo- (94% de) and enantioselectivity (96% ee) at room temperature.
