Paragraph 0102; 0103; 0114; 0115, (2018/03/25)
The invention discloses a method for preparing 3-fluorooxetane-3-methanol and an intermediate of 3-fluorooxetane-3-methanol. The method comprises the following steps of: performing a cyclization reaction on a compound represented by a formula 5 and strong base in organic solvent so as to obtain a compound represented by a formula 6, wherein R1 is a methylsulfonyl group or a p-methylphenylsulfonylgroup or a p-trifluoromethylbenzenesulfonyl group or a trifluoromethylsulfonyl group; preforming a reaction on magnesium and the compound represented by the formula 6 in organic solvent so as to obtain a compound 7. The method has the advantages of being high in yield, simple to operate and simple in post-treatment, and is suitable for large-scale production.

We have developed a novel route for the efficient synthesis of pharmaceutically significant 3-substituted oxetan-3-yl methyl alcohols starting from readily available malonates. The synthesis harnesses the diversity of malonate chemistry and allows access to a range of oxetanes, which exemplifies the versatility of this procedure.
