Nitroalkanes and Ethyl Glyoxalate as Common Precursors for the Preparation of
Both β-Keto Esters and α,β-Unsaturated Esters. — Base-promoted condensation
02- 031 of
nitroalkanes (I) and ethyl glyoxylate (II) gives good yields of nitroalcohols (III)
which are easily dehydrated to the expected nitroalkenes (IV) as precursors of β-keto
esters (VI) and α,β-unsaturated esters (VII). — (BALLINI*, R.; FIORINI, D.;
