2â?O,4â?C-Ethylene-bridged nucleic acid (ENA) phosphoramidites are highly promising modified nucleic acid monomers discovered by Daiichi Sankyo. To increase the productivity of manufacturing, we have developed a highly efficient synthetic method for ENA phosphoramidites. The basic concept of the new synthetic route is “divergent synthesis” for the preparation of four types of monomers such as A, G, C, and T. We applied stereoselective glycosylation reactions without utilizing neighboring group participation to set a common intermediate in the downstream of the route. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5Application of 76-83-5).
(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Application of 76-83-5
