title: Chemistry of phosphorus ylides. Part 33. Synthesis and antitumor activities of some new chromenone derivatives.
abstract: The reaction of nucleophilic phosphacumulene and phosphallene ylides with different chromenone derivatives was investigated. Heterocycles and carbocycles of various ring sizes and heteroatom patterns such as pyrano-, oxaphosphino-, cyclopenta-, phosphoranylidene cyclobutane-, and phospholo-chromenones were obtained. The antitumor (breast and liver) properties of some new compounds were performed in vitro. Some of these compounds were more potent than the comparative standard.
