  Synthesis of Chamaecypanone C Analogues from in Situ-Generated Cyclopentadienones and Their Biological Evaluation

  摘要：

  A rhodium-catalyzed dehydrogenation protocol for the conversion of 3,5-diarylcyclopentenones to the corresponding 2,4-diarylcyclopentadienones has been developed. With this protocol, analogues of the cytotoxic agent chamaecypanone C have been synthesized via Diels-Alder cycloaddition between the cyclopentadienones and in situ-generated o-quinols. Biological evaluation of these analogues revealed a compound with higher activity as a microtubule inhibitor and cytotoxic agent in comparison with the parent structure.

  A general approach for the synthesis of 3,5-diarylcyclopentenones was developed. Key aspects of this approach are the intramolecular Friedel-Crafts-type cyclization of vinyl chlorides and subsequent Pd-catalyzed cross-coupling reactions. The requisite vinyl chloride-bearing arylacetic acid precursors are readily available by straightforward alkylation of arylacetic acid esters and undergo cyclization to yield 3-chloro-5-aryl-2-cyclopentenones when treated with AlCl(3). The vinylogous acid chloride functionality present in these immediate products allows for further elaboration via Pd-catalyzed cross-coupling chemistry, leading to a diverse array of products.
