A directedcross-aldolreaction between two different carbonyl compounds by using 9-trifluoromethylsulfonyl-9-borabicyclo[3.3.1]nonane and tertiary amine is described. The reaction of methyl ketones with the other carbonyl compounds takes place in regiospecific manner to afford the corresponding cross-aldols in good yields through intermediates, 9-(1-methyl-1-alkenyl)oxy-9-borabicyclo[3.3.1]nonanes
