摘要
Four new dialkylphosphonate derivatives 2-5 were prepared for the first time from the guaiane-type sesquiterpene lactone estafiatin (1), which was isolated from the aerial part of Achillea nobilis. Their structures were elucidated using PMR, C-13 NMR, two-dimensional H-1-H-1 COSY, C-13-H-1 COLOC, and P-31-H-1 spectroscopy. The estafiatin phosphorylation reaction was highly chemo- and stereoselective. The antimicrobial activity of the prepared derivatives was studied.
