L-Phenylalanine has been treated with chlorosulfonic acid and the product was either hydrolyzed, ammonolyzed or reduced. The resulting sulfonic-acid and aminosulfonyl derivatives have been employed for peptide synthesis with Boc-protection of the Nα-position only. The reduction product L-(4′-SH)Phe has been protected by formation of asymmetric disulfides or with various thiol protecting groups (benzyl-
L-苯丙氨酸已用氯磺酸处理过,产物被水解,氨解或还原。将得到的磺酸和氨基磺酰基衍生物已被用于肽合成与N的将Boc-保护α仅位上。还原产物L-(4'-SH)Phe通过形成不对称的二硫键或各种硫醇保护基(苄基,甲基和乙酰氨基甲基,后者最适合于肽合成)来保护。
