摘要:虽然多硫化氢(h2Sn,N >= 2)被认为在生物学中发挥调节作用,但对其基本化学和反应性仍知之甚少.能够产生 H2Sn 的化合物是有用的工具.在这项工作中,我们发现在水溶液和有机溶剂中,在某些亲核试剂的触发下,二酰基二硫醚前体可以有效地产生 H2S2.该方法用于探索 H2S2 的氧化还原反应,例如清除 1,1-二苯基-2-三硝基苯肼自由基 (Dpph) 和还原四嗪.

标 题 :Process for the synthesis of oligonucleotides

摘要:The present invention discloses novel methods for the synthesis of oligonucleotides with nucleoside phosphoramidites on solid supports. The methods comprise the stepwise chain assembly of oligonucleotides on supports with 5′-acyl phosphoramidites. The synthesis cycles consist of a front end deprotection step which is conducted with a solution of a primary amine or a phenolate, a phosphoramidite coupling step with a 5′-acyl nucleoside phosphoramidite in the presence of an activator, a phosphite oxidation step and an optional capping step. The novel methods improve the quality of synthetic oligonucleotides due to the irreversibility of the front end deprotection step, which prevents the formation of deletion sequences, and due to the avoidance of acidic reagents in the synthesis cycles, which prevent the formation of depurination side products. The invention further discloses novel nucleoside phosphoramidite compositions wherein the phosphoramidites carry acyl front end protective groups which are cleavable with primary amines or phenolates. The invention is applicable to the synthesis of oligodeoxyribonucleotides, oligoribonucleotides and oligonucleotides with modifications in their sugar or phosphate groups.
