　　报告摘要：Our research group has been focusing on target-driven synthetic methodology development for natural product synthesis. Our strategies included employing dual-mode Lewis acid (able to induce reactions via σ- and/or π-binding mode) for developing cascade cyclization reactions, which can establish the core structures of natural products in one pot, and biomimetic approaches. Based on these strategies, we have recently developed three new cascade cyclization reactions and one 2-pyrone Diels Alder cycloaddition, and have successfully applied these methods for the synthesis of a variety of natural products including (±)-platensimycin, (±)-platencin, (–)-teucvidin, (±)-basilolide B, (±)-yezo’otogirin C, (±)-clavukerin and the aglycon of (±)-dendronobiloside A. We have also finished the synthesis of the core structure of phomactin A.
