• 論文の詳細を見る

• α, β-Unsaturated esters were made to react with N, N-dibromobenzenesulfonamide and formic acid in chloroform to give bromo-formyloxyesters. Methyl acrylate (1a), ethyl crotonate (2a), ethyl trans-cinnamate (3a), methyl tiglate (4a), methyl methacrylate (5a), and methyl phenylacrylate (6a) gave methyl 2-bromo-3-formyloxypropionate (1b), ethyl erythro-2-bromo-3-formyloxybutyrate (2b), ethyl erythro-2-bromo-3-formyloxy-3-phenylpropionate (3b), methyl erythro-2-bromo-3-formyloxy-2-methylbutyrate (4b), a mixture of methyl 3-bromo-2-formyloxy-2-methylpropionate (5b) and methyl 2-bromo-3-formyloxy-2-methylpropionate (5c), and methyl 3-bromo-2-formyloxy-2-phenylpropionate (6b) respectively in good yields.
