amines, alcohols, and phenols, and are stable to Bronsted and Lewis acids, Bronsted bases, and a wide variety of nucleophiles. However, the HTPM linkers can conveniently be cleaved by the solvolytic displacement reactions with 20% TFA. [structure: see text]
开发了一种酸碱稳定的羟基四氯二苯甲基 (HTPM) 连接体,用于聚合物支持的有机合成。这里报道的连接体用于负载羧酸、胺、醇和酚,并且对布朗斯台德酸和路易斯酸、布朗斯台德碱和多种亲核试剂稳定。然而,HTPM 连接子可以通过 20% TFA 的溶剂分解置换反应方便地裂解。 【结构:见正文】
