- Synthetic methods for (1S,4S)-2,5-diazabicyclo[2.2.2] octane and derivatives thereof
-
The invention discloses synthetic methods for (1S,4S)-2,5-diazabicyclo[2.2.2] octane and derivatives thereof, and belongs to the field of organic chemical synthesis. According to the method, 5-hydroxypyrazine-2-formate as a compound II is taken as a raw material, and high selectivity of a reaction is guaranteed through selective protection of hydroxyl and amino groups. A product obtained with the method has high yield, the by-product content is low, and the method is applicable to industrial production.
