- 論文の詳細を見る
Anodic oxidation of 5-alkyl-2-furoic acids (<B>4</B> and <B>10</B>) in protic solvents has been studied. The major products were 1-butenolides (<B>12</B>, <B>13</B>, <B>16</B>, and <B>17</B>) and γ-keto esters (<B>11</B> and <B>15</B>) and their acids (<B>14</B> and <B>18</B>). Methyl 5-<I>n</I>-hexyl-2,5-dimethoxy-2,5-dihydro-2-furoate <B>19</B> was converted into γ-keto ester <B>11</B> and its acid <B>14</B> by hydrolysis with alkali and into 1-butenolide <B>12</B> by electrolysis of the alkaline solution. A possible mechanism of the anodic oxidation of 5-alkyl-2-furoic acids has been discussed.
