STANNOUS TRIFLATE: A FACILE CROSS-ALDOL REACTION BETWEEN TWO KETONES VIA DIVALENT TIN ENOLATES
Divalent tin enolates, 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, enhance
