Reaction of acyclic enaminones with methoxymethylene meldrum's acid: synthetic and structural implications

open access: yesJournal of the Brazilian Chemical Society, 2003
The reaction of acyclic enaminones with methoxymethylene Meldrum's acid afforded N-adduct and/or C-adduct of enaminones in moderate to good yields. The regiochemistry of this reaction depends on the N-amino substituent of the enaminone. The C-adduct is a
