	abstract = {This review describes the development of a new, synthetically useful method of asymmetric synthesis in organic photochemistry. Similar in many ways to the Pasteur procedure for resolving racemic carboxylic acids and organic amines, the method relies on the use of crystalline organic salts in which the enantioselectivity of a photochemical reaction of an achiral organic ion (for example, a carboxylate anion) is governed in the solid state by the presence of an optically pure counterion (for example, an optically active ammonium ion). Such optically pure counterions are termed ionic chiral auxiliaries. Salts containing ionic chiral auxiliaries are required to crystallize in chiral space groups, which provide the asymmetric environment necessary for chiral induction. Using this methodology, we have obtained near-quantitative optical yields in a wide variety of photochemical reactions.},

	abstract = {The two ester groups have different orientations, with C=C-C=O torsion angles of -165.7(3) and -89.4(4)degrees respectively for the groups remote from and adjacent to the Cl substituent. The remote ester group is therefore fully conjugated with the C=C double bond [cos2(angle) = 0.94] and the adjacent group nonconjugated [cos2(angle) = 0], presumably as a result of steric effects.},
