概要
- 論文の詳細を見る
The photoaddition reaction of methyl 2,4-dioxopentanoate with 2,5-dimethyl-2,4-haxadiene gave a normal [2+2]adduct in only a small amount, but three isomeric dihydropyrans (<B>4–6</B>), two oxetanes (<B>7</B> and <B>8</B>), and five isomeric hydroxy keto esters (<B>9–13</B>). The mechanism and regioselectivity were discussed.
