Methyl 5-(4-fluorophenyl)-5-oxopentanoate (cas: 149437-67-2) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Asymmetric bromolactonization catalyzed by a C3-symmetric chiral trisimidazoline was written by Murai, Kenichi;Matsushita, Tomoyo;Nakamura, Akira;Fukushima, Shunsuke;Shimura, Masato;Fujioka, Hiromichi. And the article was included in Angewandte Chemie, International Edition in 2010.Product Details of 149437-67-2 The following contents are mentioned in the article:

Enantioselective bromolactonization of 5-substituted 5-hexenoic acids catalyzed by the trisimidazoline have generated 6-(Bromomethyl)-6-aryltetrahydro-2H-pyran-2-ones e. g., I (R = Ph, 4-Cl-C6H4, 4-Br-C6H4, 4-F-C6H4, 4-Me-C6H4, 4-MeO-C6H4, 2,4-Me2C6H3, 2-naphthyl, cyclohexyl). Debromination of 6-(bromomethyl)-6-(4-chlorophenyl)tetrahydro-2H-pyran-2-one leads to enantioselective derivatives II (R = H, SAc, N3) and III. This study involved multiple reactions and reactants, such as Methyl 5-(4-fluorophenyl)-5-oxopentanoate (cas: 149437-67-2Product Details of 149437-67-2).
