1-Methoxy-2-deoxy-3,5-di-O-benzoylribofuranose (CAS 108647-88-7)

1-Methoxy-2-deoxy-3,5-di-O-benzoylribofuranose is a chemically modified sugar derivative, specifically a protected form of 2-deoxyribose, where key hydroxyl groups are protected by benzoyl groups and the hydroxyl group at the 1-position is replaced by a methoxy group. This structure makes it a crucial intermediate in the synthesis of nucleosides and plays a significant role in the field of organic chemistry, particularly in the synthesis of modified nucleic acids. The presence of the 3,5-di-O-benzoyl groups protects the 3 and 5 hydroxyl groups of the ribofuranose ring, preventing them from participating in unwanted side reactions during chemical synthesis. These protecting groups are particularly important in nucleoside synthesis because they enhance the stability of the sugar moiety and allow selective reactions to occur at other sites of the molecule. The 1-methoxy group is a pivotal feature of this compound. It serves as a protective group for the 1-hydroxyl of the sugar, facilitating the introduction of nucleobases in a controlled manner to form nucleosides. This methoxy group can be removed later in the synthetic process, allowing for further functionalization or coupling with phosphates or other nucleosides to form oligonucleotides. In research, 1-Methoxy-2-deoxy-3,5-di-O-benzoylribofuranose is used extensively to study the mechanisms of nucleophilic substitution reactions on sugar moieties. By investigating how this compound reacts with various nucleophiles, researchers can better understand the steric and electronic effects that influence glycosylation reactions, which are central to the assembly of DNA and RNA molecules.
