概要
- 論文の詳細を見る
Photoadducts obtained by cycloaddition of isoprene with methyl 2,4-dioxopentanoate were converted to cyclopentene derivatives. The stereochemistry of the intermediate glycols was estabilished by chemical correlations to each other; only the <I>cis</I>-glycols were convertible to the cyclopentenes under the conditions employed, suggesting a fore-going acetylation of the hindered glycol functions.
