A convergent route has been developed to synthesize an antifungal tricyclic o-hydroxy-p-quinone methide diterpenoid and ana- logues. A Li/naphthalene-mediated reductive alkylation was employed for coupling beta-cyclocitral and the corresponding benzyl chloride, while a BBr3- mediated one-pot bis-demethylation and intramolecular Friedel Crafts alkylation was used to assemble the tricyclic molecular skeleton. The structure activity relationship of the diterpenoid was assessed on the basis of antiproliferation assays of the natural product and analogues against strains of pathogenic yeasts and filamentous fungi.

A directone-potsynthesis of phenanthrene lactams, which employs a Suzuki-Miyauracoupling/aldolcondensation cascade reaction of isoindolin-1-one with 2-formylphenylboronic acid, has been developed. The approach is used to efficiently produce a number of natural aristolactams, such as aristolactam BII (cepharanone B), aristolactam BIII, aristolactam FI (piperolactam A), N-methyl piperolactam A, and
