[2.2.1] bicyclic chiral phosphines through straightforward syntheses starting from the natural product carvone. This design rationale prompted the development of an unforeseen C-dealkenylation reaction. We have applied these organocatalysts in the asymmetric syntheses of a bevy of pyrrolines, obtained in high yields and enantioselectivities, including a biologically active small molecule, efsevin.
我们通过从天然产物香芹酮开始的简单合成方法,制备了以前未报道的P-stereogenic [2.2.1]双环手性膦家族。该设计原理促使不可预见的C-脱烯基化反应的发展。我们已经将这些有机催化剂应用于一系列吡咯啉的不对称合成中,这些吡咯啉以高收率和对映选择性(包括具有生物活性的小分子efsevin)获得。
