Article abstract of DOI:10.1246/cl.1980.1307

α-bromo-α,β-unsaturated esters and α-bromobutenolides reacted with sodium salts of methyl malonamates to afford cyclopropanes, α-methoxycarbonyllactams and 5-amino-4-methoxycarbonyl-2,3-dihydrofurans.The last compounds could be easily converted into α-met
