Novel azetidine, and particularly 2-pyridyl-azetidine, compounds are disclosed. These compounds are produced from amino-esters by a sequence comprising conversion to the sulfonamide, reduction of the ester to the alcohol, sulfonation of the resultant alcohol and cylization to the N-sulfonylazetidine. This azetidine compound may then be transformed, as desired, to various N-derivatives by substitution of hydrogen or other univalent organic groups on the secondary amine of the azetidine ring.
揭示了新型螺环丙胺化合物,特别是2-吡啶基螺环丙胺化合物。这些化合物是通过一系列步骤从氨基酯制备而来,包括转化为磺酰胺,酯还原为醇,磺化所得醇并环化为N-磺基螺环丙胺。然后,可以根据需要将这种螺环丙胺化合物转化为各种N-衍生物,通过在螺环丙胺环的次级胺上替换氢或其他一价有机基。
