Abstract

From kinetic and equilibrium measurements the activation and thermodynamic parameters of diastereomeric 2,3-dihydrobilatrienes-abc in positions “4” and “15” are deduced. Compared to bilatrienes-abc a pronounced thermal lability of these diastereomers is observed—the exocyclic double bond of the saturated lactam ring being the more labile one. This feature may be of relevance to the thermal cascades and dark reactions observed for phytochrome.
