We have prepared a previously unreported family of P-stereogenic [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出发的直接合成方法,制备了一族此前未报道的P-手性[2.2.1]双环手性膦。这种设计理念促使了一种意想不到的C-脱烯基化反应的发展。我们已将这些有机催化剂应用于多种吡咯啉的不对称合成中,这些吡咯啉的产率和对映选择性都很高,其中包括一种具有生物活性的小分子——埃夫西文。
