Abstract
2,3-Dihydrobilatrienes-abc substituted analogous to the natural chromophor of phytochrome may exhibit diastereomerism at the exocyclic double bond of the unsaturated lactam ring. Their properties are comparable to the previouslystudied bilatriene-abc diastereomers. At the exocyclic double bond of the saturated lactam ring however, diastereomers could only be prepared for thermodynamic reasons. The spectroscopic properties of the various diastereomers of five compounds were recorded and are discussed with respect to their utility in structural studies of the natural pigment system.
