New methodology in organic chemistry
Synthetic chemistry depends on reliable, high-yielding and selective reactions that access a wide variety of different structures. The discovery of new methods in synthesis is crucial to expand the range of novel compounds that can be made easily. Especially important is the development of new carbon-carbon bond-forming reactions. Our research group is studying the use of organometallic compounds in asymmetric synthesis, especially for carbon-carbon bond formation of nitrogen-containing compounds, prevalent in many biologically active molecules.
We have found that 2-lithiopyrrolidines, piperidines and other cyclic amines undergo dynamic resolution in the presence of a chiral ligand (L*), leading to highly enantioenriched 2-substituted cyclic amine products. We have determined the kinetics of enantiomerization of several chiral organolithium compounds.
Synthesis of biologically active compounds
We are using dipolar cycloaddition chemistry to access a variety of alkaloid structures. Intramolecular cycloadditions provide an efficient means to build up bicyclic and polycyclic ring systems in a rapid and stereocontrolled way.
We have shown that this chemistry is applicable to the synthesis of the core ring system of the alkaloid manzamine A, which has significant biological activity (anti-cancer, anti-malarial, and other activity). One dipole that we use is an azomethine ylide, that we make by condensation of a secondary amine with an aldehyde. Intramolecular cycloaddition sets up two new rings and up to four new stereocentres in a single step. We have prepared simpler analogues of manzamine A and other heteroaromatic compounds to probe their biological activity.
Recently, we have found that primary amines (such as amino-acids, amino-esters, hydroxylamine) can be used to condense with an aldehyde and promote a cascade process involving imine formation, cyclization, ylide formation and cycloaddition all in one pot. This chemistry provides an efficient method to prepare three rings directly from an acyclic aldehyde in a stereocontrolled way and has been applied to the total syntheses of several alkaloids (such as aspidospermidine, aspidospermine, quebrachamine and myrioxazine A).
