title: Synthesis and biological evaluation of novel C-4 aziridine-bearing paclitaxel (taxol) analogs.
abstract: Three novel C-4 aziridine-bearing paclitaxel analogs, 3-5, have been synthesized during the course of our continuing effort at C-4 modification. The key step in the synthesis is the aziridine ring formation at the C-4 position via an intramolecular Mitsunobu reaction. The syntheses and the biological evaluation of these C-4 aziridine-containing derivatives are herein discussed.
