Certain disclosed embodiments of the present invention concern a method for making biaryl compounds by combining a diene with a dienophile under reaction conditions that facilitate a Diels-Alder reaction. Certain embodiments are particularly directed to making a tetra-ortho-substituted biaryl compounds. The disclosed method may involve using novel dienes, dienophiles, or both. Similarly, certain of the biaryl compounds are novel compounds too. Additional disclosed embodiments concern a method for making useful compounds by first making a Diels-Alder adduct. The Diels-Alder adduct is then further modified or coupled to other compounds. The method can be used to make carbazoles, such as Siamenol. Disclosed biaryl compounds are useful for a number of applications, such as pharmacophores and organocatalysts.
Diels-Alder approach to polysubstituted biaryls: Rapid entry to tri- and tetra-ortho-substituted phosphorus-containing biaryls

Rapid construction: A Diels-Alder-based approach to the synthesis of highly functionalized biaryls from readily available precursors is disclosed. The utility of these biaryl templates in palladium-mediated couplings is explored along with subsequent redu
