  Selective Cross-Couplings. Sequential Stille−Liebeskind/Srogl Reactions of 3-Chloro-4-arylthiocyclobutene-1,2-dione

  摘要：

  The synthesis and initial reactivity studies of 2 are described. It was found that it participates in Stille couplings exclusively at the C-Cl site with a number of organostannanes (58-71% yield) in the absence of Cu(I). Then, these new derivatives were functionalized at the C-S site with boronic acids by switching to the Liebeskind-Srogi reaction conditions (in the presence of a Cu(l) carboxylate) to yield the bifunctionalized cyclobutenediones (44-90% yield).

  A series of novel 3,4-diaryl squaric acid analogs 4a-r related to combretastatin A-4 (CA4) using squaric acid as the cis-restricted linker were prepared and studied for their anticancer activity against selected human cancer cell lines. New compounds 4g, 4k, 4m, 4n, 4p, 4q and 4r exhibit strong activities against human leukemia cells with IC50 values of <= 20 nM and compounds 4k, 4n, 4p, 4q and 4r showed potent activities against a panel of human tumor cell lines. Compounds 4n and 4p arrest tumor cell cycle in G2-M phase. Computational modeling analysis suggests that the binding mechanism of compound 4n to the colchicine binding site on the microtubules is similar to that of CA4. (C) 2013 Elsevier Masson SAS.
