Cyclohex-2-enyl esters of homochiral (R)-Z-phenylglycine undergo completely regio- and diastereospecific addition reactions with N-phenylselenophthalimide. The resulting selenoalcohols are separable by routine chromatography and may be converted into homochiral 1,3-cyclohexonediols in which the hydroxyl groups are differentiated.
