as in ()] has an acid lability similar to that of the 4-methoxytetrahydropyran-4-yl (Mthp) protecting group under mild hydrolytic conditions [pH 2–3]; however, under the relatively more drastic conditions required for the complete removal of a 9-phenylxanthen-9-yl (Px) group, the Ctmp protecting group remains virtually intact.
1-[(2-氯-4-甲基)苯基] -4-甲氧基哌啶-4-基[Ctmp,如()]具有与4-甲氧基四氢吡喃-4-基(Mthp)相似的酸稳定性。温和水解条件[pH 2-3]下的保护基;但是,在完全除去9-苯基黄嘌呤-9-基(Px)基团所需的相对较苛刻的条件下,Ctmp保护基团实际上保持完整。
