  • Patent number: 7453011
    Abstract: Conformationally restricted polyamine compounds useful in treatment of cancer and other diseases marked by abnormal cell proliferation are disclosed. Improved methods of synthesizing such compounds are also disclosed. In one method of the invention, a carbene-bearing or carbene equivalent-bearing compound is reacted with the double bond of an alkene compound to form a cyclopropyl ring as the first step in the synthesis.
