Abstract
A procedure for the preparation of new tetracyclic quinones of the formula: ** (Formula) ** where R7 is lower alkyl of 1 to 5 carbon atoms or hydrogen; R9 is R1, R1O is hydrogen where, when R7 is lower alkyl, R9 is hydrogen and when R9 is R1 or R1O, R7 is hydrogen, where R1 is a lower alkyl group of 1 to 5 carbon atoms, phenyl-lower alkyl) or (substituted) phenyl-lower alkyl, where the substituent groups are lower alkyl or lower alkoxy, each having 1 to 5 carbon atoms, or halogen and the lower alkyl group contains 1 to 5 carbon atoms, and R1 and R8 can be the same or different.
