phytotoxins solanapyrones D (1) and E (2) have been synthesized from the decalone prepared by the domino Michaelreaction of the kinetic enolate of optically pure acetylcyclohexene with methylcrotonate. The decalone was transformed into a solanapyrone core by equilibration into thermodynamically stable trans-decalone (11), dehydroxylation, and dehydration. Condensation of a methyl acetoacetate equivalent
