Paragraph 0082; 0083; 0104; 0105, (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.

Schemes for the synthesis of 5,5'-dihydroxyleucine 3 and its 4-fluoro analog 7 involving the condensation of a suitable 'aminoacid moiety' with 2,2-dimethyl-5-iodomethyl-1,3-dioxane 15D or its fluoro analog 27A were tested.The anion of the ethyl N-diphenylmethylene-glycinate 25 gave better yields of 3 than the classical anion of diethyl acetamidomalonate.This strategy could not be successfully applied to the synthesis of 7, which could be prepared by reduction of a suitably protected 4-fluoro-4-carboxyglutamate with BMS.
