Abstract
The vicinal dianions derived from chiral succinic acid derivatives, 1, 4-bis [(4R, 5S)-3, 4- dimethyl-2-oxo-5-phenylimidazolidin-1-yl] butane-1, 4-dione and 1, 4-bis [(4S, 5R)-3, 4- dimethyl-2-oxo-5-phenylimidazolidin-1-yl] butane-1, 4-dione react with arylmethyl bromides with high diastereo-and regio-selectivity to provide the corresponding chiral α- arylmethylated succinic acid derivatives; the (R)-products are converted into (R)-β- ...
