The (S)-3- and (S)-4-bromo-α-methylbenzyl alcohols were obtained by enzymatic kinetic resolution of the appropriate racemic mixture of meta- and para-bromo-α-methylbenzyl alcohols mediated by Novozym 435 (CAL-B) in tert-butyl methyl ether as the solvent and vinyl acetate as the acetyl donor. Further reaction of these chiral bromo precursors was carried out with t-BuLi followed by addition of the appropriate elemental chalcogen and methyl iodide or diphenyl diselenide to insert the organochalcogeno group.
