Universal solid support oligonucleotide synthesis reagents, oligonucleotide synthesis processes, and reagents for cleaving oligonucleotides from solid supports are disclosed. Oligonucleotide synthesis reagents have the following general formula: SS--R.sup.6 --O--R.sup.3 I wherein SS is a solid support; R.sup.6 is ##STR1## where R.sup.5 is hydrogen or alkyl and R.sup.4 is a phosphate protecting group; and R.sup.3 is a ring moiety having vicinal groups --XR.sup.1 and --YR.sup.2 wherein each of X and Y is independently selected from the group consisting of O, S and NH and one of R.sup.1 and R.sup.2 is a blocking moiety and the other is hydrogen or a hydroxy protecting group. Oligonucleotide cleaving reagents include methylamine and/or ammonium hydroxide and trimethylamine.
揭示了用于合成寡核苷酸的通用固体支持寡核苷酸合成试剂、寡核苷酸合成过程以及用于从固体支持中裂解寡核苷酸的试剂。寡核苷酸合成试剂具有以下一般公式:SS--R.sup.6 --O--R.sup.3,其中SS是固体支持;R.sup.6是##STR1##其中R.sup.5是氢或烷基,R.sup.4是磷酸酯保护基团;而R.sup.3是一个环基团,具有邻位基团--XR.sup.1和--YR.sup.2,其中X和Y分别独立地选自O、S和NH的群,R.sup.1和R.sup.2中的一个是阻断基团,另一个是氢或羟基保护基团。寡核苷酸裂解试剂包括甲胺和/或氢氧化铵以及三甲胺。
