I was faced with this issue recently, and solved by using the Off Camera Shoe Cord 2 cable so I can point the ST-E2 backwards such that the flash sensors can pick up the IR transmission. Note that this set-up will not work if you are depending on the ETTL pre-flash to calculate the proper flash exposure. One day I will probably get a small radio triggered slave set up to overcome this line-of-sight limitation of the IR set up, but that's pricey and I don't need this set up very often to really justify the radio slave trigger. If you don't have the OCSC-2, I suppose you can always try to rig a small mirror in front of the ST-E2 and reflect the IR signals backwards, you may even try folding a highly reflective piece of material into a V shape and place in front of the ST-E2 to help directing the IR signals to the respective flashes.
