Koseki, Yoshitaka; Watanabe, Toshihiro; Kamishima, Takaaki; Kwon, Eunsang; Kasai, Hitoshi published an article in 2019, the title of the article was Formation of Five-Membered Carbocycles from d-Glucose: A Concise Synthesis of 4-Hydroxy-2-(hydroxymethyl)cyclopentenone.Recommanded Product: (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate And the article contains the following content:
A concise synthesis of 4-hydroxy-2-(hydroxymethyl)cyclopentenone (I) has been accomplished from D-glucose by a three-step sequence that features a catalyst-free hydrothermal reaction of D-glucal, which is readily obtained from D-glucose. Optimization of the reaction conditions for synthesizing I was performed by changing the temperature and reaction time. The treatment of D-glucal under the optimal conditions, i.e., at 120 °C for 24 h, provided I in the highest isolated yield of 61%. I would become a versatile intermediate for the synthesis of various fine chems. having a cyclopentenone structure from cellulosic biomass. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Recommanded Product: (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate
