Abstract

The decarboxylative photocyclization of potassium 2-azabicyclo[3.3.0]octanoate ethylene linked to phthalimide reads to a mixture of two diastereoisomeric products. The overall noninduced diastereoselectivity is remarkably high, indicating a preference of spin-orbit coupling controlled 1,7-biradicalcombination process, Memory of chirality vanished due to tree rotation about the connecting spacer bonds.
