Synthesis of Helical Molecules Based on 5,6,6a,7,8,12b-Hexahydrobenzophenanthrene-5,8-dione

Article abstract of DOI:10.1071/CH9951707

Synthetic routes based on Newman'synthesis of a number of polycyclic aromatic hydrocarbons were modified and developed to give a convenient preparation (Scheme 1) of 11 helical molecules formally based on hexalindione (1).In contrast to Newman's work, we
