Abstract

An improved annulation sequence is presented, making use of the one-pot cyclization of 5-nitropentan-2-one and cyclopent-2-enone diesters to afford 7-methyl-4-nitro-1-oxohydrindene derivatives. Functional group elaborations of these intermediates lead to a series of the title compounds, which could be readily converted to the tricyclic moieties of strigol and its analogues of biological importance.
