4-Aminotetrahydropyran contains the tetrahydropyran ring, which is the most frequently reported three-dimensional ring system in marketed drugs, and is second only to the phenyl ring when two-dimensional rings are included. It can be used as reactant/reagent in synthesis of aminothiazole compounds for use in treatment of cancer. Its scaffold is very useful in the drug discovery for cancer treatment.

- It can be used as organic synthesis intermediates and pharmaceutical intermediates, mainly used in the laboratory research and development process and the chemical and4-Aminotetrahydropyran
- pharmaceutical synthesis process. Preparation Take 4-cyanotetrahydropyran, sodium hydroxide solution (or potassium hydroxide 4-Aminotetrahydropyransolution) as raw materials to synthesize 4-formamide tetrahydropyran, and then slowly add sodium hypochlorite solution to 4-formamide Chemicalbook tetrahydropyran (Or sodium hypobromite solution), then heated to reflux, decarboxylation to produce 4-aminotetrahydropyran. Put all the reaction materials in a pot to react, and by selecting appropriate reaction conditions, 4-aminotetrahydropyran is synthesized.
