Ethyl 1-Boc-5-oxo-hexahydro-1H-azepine-4-carboxylate was used in the study of synthesis and study of selective 5-HT2C receptor agonist and its activity, and structure-activity relationship of pyrimido[4,5-d]azepines.
Ethyl 5-oxoazepane-1-carboxylate was prepared by a ring expansion reaction using 4-oxopiperidone hydrochloride and ethyl diazoacetate as starting materials, which was directly used in the next step without purification. The target compound 1-BOC-5-oxoazepane-carboxylic acid ethyl ester was prepared by condensation reaction with di-tert-butyl dicarbonate under alkaline condition.
