Hydrogenated naphthalene derivativesQ 1010 A Two-Step Reaction Sequence for the Synthesis of Tetrahydronaphthalenes. —
Diels—Alder reaction of a boron-functionalized enyne with substituted alkenes affords dihydroaromatic boronic esters (III) and (XXI). The latter are applied in further Diels—Alder sequences to give highly substituted and functionalized products in acceptable to very good yields. Five new C—C bonds from 4 simple components are formed in this process. — (HILT*, G.; LUEERS, S.; SMOLKO, K. I.; Org.
