The first catalytic asymmetric [3 + 2] cycloadditions of Schiff bases of alpha-aminophosphonates with olefins have been developed. Chiral silver amide complexes bearing (R)-DTBM-SEGPHOS worked well as catalysts for the first time, and proline phosphonic analogues were obtained in high yields with excellent exo- and enantioselectivities.
首次发展了手性亚膦酸酯烯胺Schiff 碱与烯烃的[3+2]环加成反应的催化不对称反应。手性银酰胺配合物(R)-DTBM-SEGPHOS 首次作为催化剂表现良好,脯氨酸膦酸类似物以高产率和优异的 exo-和对映选择性获得。
