Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations.127956-11-0, Name is Methyl 4-oxotetrahydro-2H-pyran-3-carboxylate, molecular formula is C7H10O4. In a Patent，once mentioned of 127956-11-0, name: Methyl 4-oxotetrahydro-2H-pyran-3-carboxylate
The invention relates to a synthetic beta – difluoro beta – keto ester carboxylic acid compound. In most of the method solves the yield is low, not amplifying the production technical problems. The technical scheme of the present invention: beta – keto ester synthesis by beta – difluoro carboxylic acid, which is characterized in that: comprising the following steps, the invention commercially available beta – keto ester of the raw materials, by the presence of HF, and SF4 The reaction produces beta – […] ester, through hydrolysis of the acid conditions, to obtain the beta – difluoro carboxylic acid. The invention relates to a molecule and its derivatives can be involved in the synthesis of phosphodiesterase (PDEs) in particular PDE2 inhibitor drug. (by machine translation)
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C7H10O4, you can also check out more blogs about127956-11-0
