Planar Dehydro[8]annulenes and Their Ramifications: Substituted Tribenzo[a,c,e]cyclooctenes and Tetrabenzo[a,c,e,g]cyclooctenes

Our research endeavors on planar dehydro[8]annulenes were broadened into areas concerning syntheses and studies of strategically substituted tribenzo[a,c,e]cyclooctenes and tetrabenzo[a,c,e,g]cyclooctenes. Further conversion of these scaffolds led to novel molecules containing central planar eight-membered ring compounds.
