Photolabile protecting groups have proven their usefulness on many occasions. Their versions as linkers are however less attractive, as robustness and real orthogonality become critical issues. Safety-catch systems, where a preliminary activation phase is necessary, circumvent the problem of premature cleavage. In this work, we introduce a new safety-catch photolabile protecting group, whose cleavage
光不稳定的保护基已经在许多场合证明了其有用性。然而,由于健壮性和真正的正交性成为关键问题,它们作为链接器的版本吸引力不大。安全捕获系统需要一个初步的激活阶段,可以规避过早分裂的问题。在这项工作中,我们引入了一个新的安全捕捉光不稳定的保护基,其裂解需要同时存在光和化学促进剂。
