Abstract
Conjugated addition of primary nitroalkanes to α,β-unsaturated ketones or α,β-unsaturated esters, in the presence of two equivalents of DBU, allows the one-pot prepration of γ-diketones or γ-keto esters, respectively. When 2-aryl-1-nitroethane derivatives are employed as starting nitroalkanes in the reaction with α,β-unsaturated ketones, the one-pot formation of cyclopentenones is observed.
Key words
nitroalkanes - γ-diketones - γ-keto esters - cyclopentenones - DBU
