  A New Access to Piperidino-cyclopiperidinecarboxamides - constrained analogues of a pharmaceutical used diaminic building block

  摘要：

  6-Piperidino-3-azabicyclo [3.1.0]hexane-6-carboxamide diastereomers 1a and 2a represent conformationally rigid analogues of 3a which is a building block in some pharmaceutical compounds. A new access to these compounds 1a and 2a was found via the cleavage of bicyclic N,N-acetal 6 with hydrocyanic acid as the stereodetermining step. Reaction of derivatives 1a and 2a with bromodiphenyl-butyronitrile 14 gave cyclopiritramide isomers 1c and 2c, respectively. Qualitative preliminary investigations showed different affinities of 1c and 2c to the opiate-mu receptor. These results were discussed on the basis of an X-ray structural analysis of cyclopiritramide isomer 2c.1-Benzylcyclopiperidine derivatives 1d and 2d were used as model systems for studying the conformation of cyclopiritramide isomer 1c and 2c, respectively.
