Asymmetric [2 + 2] olefin cross photoaddition in a self-assembled host with remote chiral auxiliaries
Abstract
Remote chirality at the periphery of a self-assembled cage brings about the slight twist of aromatic rings, which is yet sufficient to induce considerable asymmetric induction (up to 50% ee) in the hitherto unknown [2 + 2] cross photoadditions of fluoranthenes.
