标题:一种o,O-二乙基硫代磷酰氯的绿色合成工艺
摘要:一种o,O‑二乙基硫代磷酰氯的绿色合成工艺,涉及化学合成领域,其先将o,O‑二乙基二硫代磷酸酯在低温下与氯气反应,得到o,O‑二乙基硫代磷酰氯的粗品,再将上述粗品移至高温下反应,让残留的o,O‑二乙基二硫代磷酸酯与氯气进一步反应完全.同时,在高温反应时,通过复合催化剂的使用来防止多聚化合物的生成,并充分反应掉一氯化硫杂质,使副产物硫磺呈结晶状态,使产品更易分离纯化.此外,通过加负压将hcl,含硫有臭味气体抽走,进尾气吸收,防止污染空气.整个反应过程中无需加入工艺水,因此不会产生废水,减少了含硫含磷废水的处理成本.该工艺的操作简单,原料易得,反应条件温和,并且污染小,具有环境友好性.

摘要:The invention concerns a method for preparing monomer nucleotides or nucleotide analogues comprising the steps of: (1) coupling a soluble polyethylene glycol support provided with at least one diacid or ether-acid linker and a monomer nucleoside or nucleoside analogue to an amine group or hydroxyl group of the nucleoside with the aid of a coupling agent; (2) at least one step for phosphorylation of said nucleoside or nucleoside analogue coupled to said support with a phosphorylation agent; (3) cleavage of said support and recovery of at least one monomer nucleotide or nucleotide analogue. The nucleotides prepared are biological tools.
