Abstract

Highly efficient regiospecific routes to potentially carcinogenic polycyclic aromatic hydrocarbons such as substituted benzo [c] phenanthrenes, benzo [c] fluorenes, 16, 17- dihydro-11-methyl-15 [H] cyclopenta [a] phenanthrene, 5-methyl-7, 8, 9, 10- tetrahydrochrysene and 1, 4-dimethylphenanthrene have been developed. The overall strategy involves our aromatic annulation protocol through base induced conjugate ...
