Triple play: The title reaction of 1 with simple aldehydes gives 3,5,7‐trisilyloxy aldehydes in high yields and diastereoselectivities with extremely low catalyst loading (see scheme). Iodobenzene facilitates the third aldol reaction by apparently acting as a Lewis base towards the silyl catalyst. Tf=trifluoromethanesulfonyl.
