PROBLEM TO BE SOLVED: To provide synthesis methods of 5-hydroxy-6-methoxypiperidine-2-carboxylic acid derivatives and 5-oxopiperidine-2-carboxylic acid derivatives more safely than ever by using inexpensive raw ingredients. SOLUTION: In the provided method, a compound expressed by the following formula [X] is manufactured from a compound expressed by the following formula [I] through steps (1) through (9) [either steps (4) and (5) or steps (6) and (7) in the case of steps (4) through (7)].

(Chemical Equation Presented) Herein, we report a diastereoselective synthesis of the natural product (2S,5R)-5-hydroxypipecolic acid and 6-substituted derivatives thereof. The key step in the synthetic sequence is a novel highly diastereoselective epoxidation reaction of an enantiomerically pure cyclic enamide intermediate.
