Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 7748-36-9, formula is C3H6O2, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Reference of 7748-36-9
Strassfeld, Daniel A.;Algera, Russell F.;Wickens, Zachary K.;Jacobsen, Eric N. research published 《 A Case Study in Catalyst Generality: Simultaneous, Highly-Enantioselective Bronsted- and Lewis-Acid Mechanisms in Hydrogen-Bond-Donor Catalyzed Oxetane Openings》, the research content is summarized as follows. Generality in asym. catalysis can be manifested in dramatic and valuable ways, such as high enantioselectivity across a wide assortment of substrates in a given reaction (broad substrate scope) or as applicability of a given chiral framework across a variety of mechanistically distinct reactions (privileged catalysts). Reactions and catalysts that display such generality hold special utility, because they can be applied broadly and sometimes even predictably in new applications. Despite the great value of such systems, the factors that underlie generality are not well understood. Here, we report a detailed investigation of an asym. hydrogen-bond-donor catalyzed oxetane opening with TMSBr that is shown to possess unexpected mechanistic generality. Careful anal. of the role of adventitious protic impurities revealed the participation of competing pathways involving addition of either TMSBr or HBr in the enantiodetermining, ring-opening event. The optimal catalyst induces high enantioselectivity in both pathways, thereby achieving precise stereocontrol in fundamentally different mechanisms under the same conditions and with the same chiral framework. The basis for that generality is analyzed using a combination of exptl. and computational methods, which indicate that proximally localized catalyst components cooperatively stabilize and precisely orient dipolar enantiodetermining transition states in both pathways. Generality across different mechanisms is rarely considered in catalyst discovery efforts, but we suggest that it may play a role in the identification of so-called privileged catalysts.
7748-36-9, Oxetan-3-ol is a useful research compound. Its molecular formula is C3H6O2 and its molecular weight is 74.08 g/mol. The purity is usually 95%.
Oxetan-3-ol is a synthetic hydroxy compound with the chemical formula C6H12O3. It is an organic solvent that can be used in reactions involving vinyl alcohol and oxetane, such as ring-opening polymerization and cationic polymerization. Oxetan-3-ol has also been shown to react with ethyl bromoacetate to form the corresponding oxetane, which can be used as a bioisostere for chloropropane, a potential replacement for chlorofluorocarbons., Reference of 7748-36-9
