2′- and 3′- cholesterol-conjugated adenosine and cytosine nucleoside building blocks: synthesis of lipidic nucleic acids was written by Manoharan, Muthiah;Inamati, Gopal;Tivel, Kathleen L.;Conklin, Boyd;Ross, Bruce S.;Cook, P. Dan. And the article was included in Nucleosides & Nucleotides in 1997.Name: N-(5-Bromopentyl)phthalimide This article mentions the following:
2′- And 3′- cholesterol-conjugated adenosine and cytosine nucleoside building blocks for lipidic nucleic acids were prepared Large scale synthesis and purification of two oligonucleotides were completed in 100 mg scale. In the experiment, the researchers used many compounds, for example, N-(5-Bromopentyl)phthalimide (cas: 954-81-4Name: N-(5-Bromopentyl)phthalimide).
N-(5-Bromopentyl)phthalimide (cas: 954-81-4) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon鑱砨romine bond is electrophilic in nature. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Name: N-(5-Bromopentyl)phthalimide
