P. Renaud et T. Bourquard, ORTHO-SUBSTITUTED ARYL SULFOXIDES DESIGNED FOR HIGHLY DIASTEREOSELECTIVE RADICAL REACTIONS, Tetrahedron letters, 35(11), 1994, pp. 1707-1710
Radical allylation of 1-arenesulfinylethyl radicals has been examined
for different ortho-substituted aryl groups. High level of diastereose
lectivity (up to 95 % ds) has been achieved with the o-chlorobenzenesu
lfinyl group. Rationalization of the results based on ground state con
formation of the radicals is presented.
