Dr G. Richard Stephenson obtained his Ph.D. in 1978 through research in the group of Lord Lewis FRS at the Cambridge University Chemical Laboratory (Cambridge, UK). Following this he moved to the Research School of Chemistry, Australian National University (Canberra) to spend four years as a Research Fellow in the group of Sir Arthur J. Birch FRS, returning to Cambridge in 1982 as Senior Research Fellow at Girton College, Cambridge. Stephenson now holds a readership (1995) in the School, after promotion through lecturer (1991) and senior lecturer (1993), following an initial period of full-time research at UEA with support from the Royal Society as a University Research Fellow (1984-91).
In 2000, Stephenson was Visiting Professor at the Université de Caen; in 2001, Invited Professor at Université Paris VI; and in 2003, he was Invited Professor at the Université Catholique de Louvain. Stephesnon held a Visiting Fellowship at the Australian National University in 2006.
Selected Publications
Selective synthesis and reactivity of h5-1 arylcyclohexadienyliron complexes
D.A. Owen, A.V. Malkov, I.M. Palotai, C. Roe, E.J. Sandoe, G.R. Stephenson
Chem. Eur. J., 2007, 13, 4293-4311.
DOI 10.1002/chem.200601513
Journal title: Chemistry - A European Journal; Month/year of publication: May 2007 Pagination: 4293-4311 Volume: 13 (15); ISSN: 1521-3765
This paper presents a versatile general method to access aryl-substituted electrophilic metal complexes and opens the way for a new “C12 building block” approach to the synthesis of alkaloids.
Stereomanipulation of h5-1-aryl cyclohexadienyliron complexes
C.E. Anson, A.V. Malkov, C. Roe, E.J. Sandoe, G.R. Stephenson
Journal title:: European Journal of Organic Chemistry; Publication date: 01/11/2007; Pagination: 196-213 Volume: ; ISSN: 1099-0690
The paper establishes that bioactive alkaloids can be approached by the use of stereocontrolled electrophilic organoiron multihapto complexes. Additional electron density on the arene flattens structures of the electrophiles allowing correct nucleophile addition. Impacts on synthesis design.
Intramolecular Asymmetric Heck Reactions: Evidence for Dynamic Kinetic Resolution Effects.
M.C. McDermott, G.R. Stephenson, D.L. Hughes, A.J. Walkington
Org. Lett., 2006, 8, 2917-2920.
DOI 10.1021/ol0606132
The conformations of the iodoanilide substrates determine the direction of stereocontrol. In this work symmetrised substrate analogues have been examined to simplify the interpretation of conformational effects. Impacts in industrial applications of palladium catalysed coupling reactions.
