I. Radical Cyclizations Mediated by Transition Metal Hydrides II. Study toward the Total Synthesis of Pluraflavin A III. Cytoprotective Polyacetylenes Inspired by Panaxytriol
… synthesis and in vitro evaluation of a series of polyacetylenes inspired by the Ginseng-derived natural product, panaxytriol. Three series of analogs were synthesized by a convergent route featuring the Cadiot-Chodkiewicz reaction. The analogs were tested for their ability to induce cytoprotective …
