asymmetric insertion reactions of donor–donor carbenoids, i.e., those with no pendant electron-withdrawing groups, are reported. This process enables the synthesis of densely substituted benzodihydrofurans with high levels of enantio- and diastereoselectivity. Preliminary results show similar efficiency in the preparation of indanes. This new method is used in the first enantioselective synthesis of an
报告了供体-供体类卡宾的第一个不对称插入反应,即那些没有吸电子侧基的反应。该过程能够合成具有高水平对映选择性和非对映选择性的密集取代的苯并二氢呋喃。初步结果显示制备茚满的效率相似。这种新方法用于首次对映选择性合成低聚白藜芦醇天然产物(E-δ-viniferin)。
