Reactions of cyclohexadienes. Part VI. Further reactions of Diels–Alder adducts from 1-methoxycyclohexadienes
Abstract
Diels–Alder adducts of some 1-methoxycyclohexa-1,3-dienes and but-1-en-3-one, after formylation or acetylation, are rearranged by acid, and can be ultimately converted into derivatives of cis-decahydronaphthalene-2,7-dione.
