Compounds which are capable of generating acid on photolysis are disclosed, and the uses of these compounds, especially for deprotecting the termini of nucleic acid molecules or peptides during synthesis of arrays. The compounds described herein may be employed in the detritylation of 5′-O-dimethoxytrityl (DMT) protected nucleotides by photolysing the compounds to generate an acid capable of removing the DMT group allowing oligonucleotide arrays to be synthesised using readily available 5′-O-DMT-nucleoside-3′-O-phosphoramidite monomers conventionally used in solid phase nucleic acid synthesis. A method of avoiding the effects of stray light in projection lithography techniques is also disclosed.
本文披露了能够在光解作用下产生酸的化合物,并介绍了这些化合物的用途,特别是在合成阵列期间去保护核酸分子或肽的末端。本文所描述的化合物可用于通过光解产生能够去除DMT基团的酸来去除5'-O-二甲氧基三苯基甲酰(DMT)保护的核苷酸,从而使用常规固相核酸合成中使用的易得的5'-O-DMT-核苷酸-3'-O-磷酸酰胺单体合成寡核苷酸阵列。本文还披露了一种避免投影光刻技术中杂散光影响的方法。
