Asymmetrical photochemical reactions were performed within zeolites. Two strategies achieved chiral induction. The first involved the asymmetrical modification of the zeolite by adsorption of chiral organic molecules and subsequent irradiation of the substrate within the chiral environment. The second involved attaching a chiral handle to the photochemically reactive molecule and conducting the reaction within the zeolite. Tropolone ethers went through a 4-p disrotatory electrocyclization to yield a bicyclic product. Adamantyl ketones underwent the Norrish-Yang reaction to yield cyclobutanols. Mesityl acetophenones experienced d-hydrogen abstraction to yield cyclized products. These reactions were evaluated within zeolites for asymmetric induction.
