All in order: Bicyclic and tricyclic chemotypes were accessed through the title transformations. By subsequent pairing of installed functional groups using Heck cyclization or [2+2] photocycloaddition, the synthesis of tetracycles, pentacycles, and condensed polycycles has been achieved with high stereochemical and skeletal variation.
