产品详细信息

Packaging
25 g in glass bottle
Application
This electrophilic resin is used for the attachment of amines alcohols, sulfamates, thiols and phenols using the Fmoc strategy. This resin is an intermediate between the Merrifield resin and the trityl chloride resin in term of acid lability. The carbocation formed during the cleavage reaction is more stable than Merrifield resin but less stable than the trityl chloride resins. The substituents on the benzhydryl chloride can be chosen in order to obtain a less acid labile resin (2-chloro) or a more acid labile resin (4-Methyl) than the benzhydryl chloride resin.

Application
此亲电树脂用于采用 Fmoc 法附接胺、醇、氨基磺酸酯、硫醇和酚。此树脂的酸不稳定性介于氯甲基树脂和三苯甲基氯树脂之间。裂解反应过程中，此树脂形成的碳正离子的稳定性高于氯甲基树脂，而低于三苯甲基氯树脂。可选择二苯氯甲烷上的取代基，以获得酸稳定性比二苯氯甲烷树脂更低（2-氯）或更高（4-甲基）的树脂。
