COA of Formula: C9H9BrO2In 2020 ,《On the electron withdrawing nature of ethers in glycosylation chemistry》 appeared in Carbohydrate Research. The author of the article were Marqvorsen, Mikkel H. S.; Brinkoe, Anne; Jensen, Henrik H.. The article conveys some information:
The present review paper is a commentary on the electronic effects that protecting groups exert on glycosylation chem (with new data). Specifically, its purpose is to rectify the misguided use of the term electron donating benzyl groups, which hardly makes sense in the context of protecting groups on alcs. in saturated systems such as carbohydrates. It is argued that benzyl ethers (OBn) should rightfully be referred to as being inductively electron withdrawing, even if they are less so than benzoyl esters (OBz). In the experimental materials used by the author, we found Benzyl 2-bromoacetate(cas: 5437-45-6COA of Formula: C9H9BrO2)
Benzyl 2-bromoacetate(cas: 5437-45-6) has been used in the alkylation of (-)-2,3-O-isopropylidene-D-threitol that afforded lipopeptide, 2-[(4R,5R)-5-({[(9H-fluoren-9-yl)methoxy]carbonylaminomethyl}-2,2-dimethyl-1,3-dioxolan-4-yl)methoxy]acetic acid.COA of Formula: C9H9BrO2
