A series of compounds designed to adopt a conformation similar to the tubulin-binding T-Taxol conformation of the anticancer drug paclitaxel has been synthesized. Both the internally bridged analogs 37-39, 41 and the open- chain analogs 27-29 and 43 were prepared. The bridged analogs 37-39 and 41 were synthesized by Grubbs' metatheses of compounds 30-32 and 33, which, in turn, were prepared by coupling beta-lactams 24-26 with alcohols 22 and 23. Both the bridged and the open- chain analogs showed moderate to good cytotoxicity. (C) 2011 Elsevier Ltd. All rights reserved.
