Model compounds have been studied to elucidate the relative orientation of enolate and carbonyl moieties in the aldol reaction. The syntheses of these compounds have been achieved from a common precursor derived from fragmentation of adamantane. Models of the limiting transition structures reveal that the cyclization must proceed through either a synclinal or antiperiplanar orientation of the aldehyde
