The effects of various aromatic substituents in both ephedrine and a cyclic phosphoric acid on the quality of resolution via diastereomeric salt formation are investigated. The diastereoselective synthesis of a novel series of chloro-substituted ephe

Benzo[b]thiophene-2-carboxaldehyde undergoes condensation with 4-methylpyridine and with 2-methylquinoline to produce trans-diarylethenes (52% and 76%, respectively). The former alkene photocyclizes in cyclohexane to yield [1]benzo[2,3-h]isoquinoline
