Kovackova, Sona published the artcileThe synthesis of piperidine nucleoside analogs-a comparison of several methods to access the introduction of nucleobases, Formula: C4H3Cl2N3, the publication is Tetrahedron (2011), 67(7), 1485-1500, database is CAplus.
This work deals with the synthesis of piperidine and hydroxypiperidine analogs of nucleosides, e.g. I. Starting from com. available 3-hydroxypiperidine, proline or 4-hydroxyproline, a series of piperidine derivatives of both purine and pyrimidine nucleobases was prepared Various methods of nucleobase attachment were evaluated. The prepared compounds were tested for cytostatic, antibacterial, and antiviral properties but no significant activity was found.
