Stereoselective synthesis and antitumoral activity of Z-enyne pseudoglycosides

Abstract

An efficient approach for the synthesis of Z-1,3-enynes based on the coupling reaction of Z-vinyl tellurides and alkynes containing a pseudoglycoside moiety is described. The products were obtained in good yields via a stereoselective way. Preliminary screening against three tumor cell lines indicated that the synthesized compounds are promising intermediates for the synthesis of an array of more potent target structures.
