용도Methyl 2,3-Butadienoate is used as an reactive electrophilic reagents for nucleophilic addition, Michael addition, [2 + 2], [2 + 3], and [2 + 4] cycloadditions, and hetero-Cope rearrangements.
Methyl 2,3-Butadienoate is most conveniently obtained via a Wittig reaction of [E(R)CHPPh3]+X- or E(R)C=PPh3 and RR′CHCOCl (R, R′ = H, alkyl) in the presence of Triethylamine in CH2Cl2.[1]Alternatively, the Wittig reaction can be performed with the corresponding ketenes.[2]
