Synthesis of 1,2-bis(methoxyamino)cycloalkanes from alicyclic 1,2-bis(hydroxyamines)
摘要:
Derivatives of 1,4-dihydroxypiperazine-2,3-dione were obtained by reaction of cis-1,2-bis(hydroxyamino)cycloalkanes with diethyl oxalate. Their alkylation with CH2N2 or Mel afforded 1,4-dimethoxypiperazine-2,3-diones. Hydrolysis of the latter gave 1,2-bis(methoxyamino)cycloalkanes.
Synthesis of aliphatic 1,2-bishydroxylamines from 1,3- dihydroxyimidazolidines.
摘要:
Reduction of 1-hydroxy-3-imidazoline-3-oxides with NaBH4 gives 1,3-dihydroxyimidazolidines. The latter on subsequent treatment with NH2OH.HCl in EtOH or in hydrochloric acid afford 1,2-bishydroxylamines. An X-ray study of 1,2-bishydroxylaminocycloalkanes has shown them to be cis-configurated.
