Stereochemistry of the photochemical Berson-Willcott rearrangement of methyl 2,3-benzonorcaradien-7-ylacetate to methyl 2,3-benzobicyclo-[3.2.0]hepta-2,6-dien-4-ylacetate
Abstract
The photochemical Berson-Willcott skeletal rearrangement of methyl 2,3-benzonorcaradien-7-ylacetate to methyl anti-2,3-benzobicyclo[3.2.0]hepta-2,6-dien-4-ylacetate was found to proceed with inversion of configuration at C-7.
