The synthesized phosphorus-containing fluorocopolymer has chain linearity and narrow molecular weight distributions. It has applications as a lubricant additive that provides friction-reduction, anti-wear, and corrosion protection properties.
专利号:US-2015018579-A1 优先权日:2012-02-22 标题:Synthesis of high purity dmt-c3-disulfide phosphoramidite 发明人:SRIVASTAVA SURESH C; THATIKONDA SANTHOSH K; SHUKLA PRAVEEN; SRIVASTAV SANT KUMAR 权利人:SRIVASTAVA SURESH C; THATIKONDA SANTHOSH K; SHUKLA PRAVEEN; SRIVASTAV SANT KUMAR 摘要:The 5′ and 3′-thiol modified oligonucleotides are attractive tools with a vast number of potential applications in the field of nucleic acid chemistry. There is a strong interest in developing new disulfide compounds or to optimize synthesis of existing disulfide modifiers, which are efficient in generating the 3′- or 5′-end reactive thiol group. Various synthetic protocols have been employed to synthesize pure 3-((3-(bis(4-dimethoxytrityl)propyl)di-sulfanyl)propyl 2-cyanoethyl diisopropylphosphoramidite (compound 2) starting from 3-(dimethoxytrityl)propyl)disulfanyl)pro-pan-1-ol, (compound 1). Herein, we describe an efficient, reproducible synthetic and purification protocol for target compound 2 from the compound 1. It is noteworthy that our reaction conditions were reproducible even at multi-gram scale (27 g) with a purity level as achieved in a small scale.
