Synthesis and Stereochemistry of Tropane 6-Spiro-hydantoins
摘要:
The synthesis of several representatives of the previously unknown N-alkyl-nortropane-6-spirohydantoin ring system by Bucherer-Bergs reaction of 8-alkyl-8-azabicyclo[3.2.1]octan-6-ones is described. 3-Oxo derivatives of the parent structure were also prepared. The stereochemical outcome of the Bucherer-Bergs reaction is discussed on the basis of H-1-nmr and C-13-nmr data.
