Cascade reactions of C2-C4 oxygenates on TiO2  and hydrogenation-dehydrogenation on metal sites lead to stable aldol condensation rates and to parallel esterification reactions, involving common enolate intermediates formed in the sole kinetically-relevant step on TiO2.  A correlation between the reactant structure and its reactivity is unveiled both experimentally and theoretically.
