Some common heterocyclic compound, 115118-68-8, name is Diisopropyl 3,3-dimethoxycyclobutane-1,1-dicarboxylate, molecular formula is C14H24O6, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 115118-68-8
Reference Example 3 3-Oxocyclobutane carboxylic acid To diisopropyl 3,3-dimethoxycyclobutane-1,1-dicarboxylate (760 g) obtained from Reference example 2, 20% of hydrochloric acid solution (3.2 L) was added and the mixture was refluxed for four days. After that, the reaction solution was extracted with ethyl acetate, and then the organic layer was dried over magnesium sulfate. Solids were removed, the filtrate was dried under reduced pressure to obtain the title product (700 g). 1H-NMR (CDCl3): 11.2 (1H, s), 3.41 (5H, m).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 115118-68-8, its application will become more common.
