英文摘要: A direct asymmetric tandem reaction of alpha-nitro ketones with beta,gamma-unsaturated alpha-ketoesters was found to be catalyzed by a bifunctional rosin-derived thiourea and gave 5-nitro-2-actoxy1-2-pentenates in excellent ee values and yields, a much better result than previously reported. Furthermore, through theoretical analysis, literature research and experimental verifications, a new mechanism involving an inverse-electron-demand Diels-Alder (IEDDAR) and a retro-Henry reaction was proposed.
