—— | 2-Brom-2-cyan-N-methyl-acetamid | 52765-37-4 | C4H5BrN2O | 177.0 |
2,5-Dihydro-2-oxofuran-3-carboxamides were synthesized by a one-pot two-step reaction catalyzed by sodium methoxide. Readily available tertiary α-hydroxyketones were condensed with substituted cyanoacetamides to give 2-imino-2,5-dihydrofuran-3-carboxamides that, without isolation, were hydrolized to the title products.
