The cleavage of the 2,2,2-trichloro-1,1-dimethylethoxycarbonyl (trichloro-tert-butoxycarbonyl, TCBOC) protective group for amino and hydroxy functions by tin(II) tris[benzenethiolate] in the presence of tetrabutylammonium cobalt(II) phthalocyanine-5,12,19,26-tetrasulfonate is reported. This combination is superior to previously used deblocking reagents for the TCBOC-group.
据报道,在四丁基氨钴(II)酞菁-5,12,19,26-四磺酸盐存在下,三[苯硫酚]锡(II)可裂解氨基和羟基功能的 2,2,2-三氯-1,1-二甲基乙氧基羰基(三氯-叔丁氧羰基,TCBOC)保护基。这种组合比以前使用的 TCBOC 族解锁试剂更为优越。
