title = "The fate of the tert-butylsulfinyl auxiliary after acid-promoted cleavage-a method for recycling t-BuSONH2",
abstract = "Ellman's chiral auxiliary is converted into tert-butylsulfinyl chloride on sulfinamide deprotection with HCl and can be recovered in high yield upon treatment with ammonia. The enantiopure auxiliary can be obtained by trapping the sulfinyl chloride with a chiral alcohol followed by treatment of the resulting sulfinate ester with LiNH2.",
