Sažetak
The photodimerisation of cyclobutene-1,2-diesters has been employed to prepare novel bis-heterocycles containing the following range of subunits: b-lactam (38, 39, 42, 43, 48, 49), dimethoxypyrimidines (29-32), acyl proline (56), 7-oxanorbornene (18) and dipyridylpyridazine ligand (20). Racemic starting materials are observed to afford diastereomeric mixtures of C2- and Cs-dimers, while symmetrical or enantiometic substrates yield single dimeric photoproducts.
