A highly diastereoselective cross aldolreaction is developed using divalent tin enolates formed from stannous trifluoromethanesulfonate and carbonyl compounds. The reaction is extended to a highly enantioselective cross aldolreaction employing chiral diamines derivedfrom (S)-proline as ligands.

Divalent tinenolates, formed from stannous triflate and ketones, react with a second ketone under mild conditions to afford the corresponding cross-aldol products in good to excellent yields. In the case of the cross-coupling with aromatic ketone, enhanced threo-selectivity was observed.
