Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 99974-66-0, name is Diethyl 3-hydroxycyclobutane-1,1-dicarboxylate, A new synthetic method of this compound is introduced below., COA of Formula: C10H16O5
To a solution of compound BB2-C (18 g, 0.0833 mol) in DCM (200 mL) was added PCC (37 g, 0.176 mol) and the mixture was stirred for four hours at room temperature. The solution was filtered through a silica gel column and the residue was washed with DCM/MeOH 98/2 and then filtered through a similar column. The combined fractions were evaporated under reduced pressure to provide the desired compound. TLC system; Petroleum ether: ethyl acetate (9: 1), RF = 0.3. Yield: 1 1 g, 62 %.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
