  a new synthetic strategy is demonstrated, where arynes are converted into aryl anion equivalents by treatment with phosphines and a base. The addition of phosphines to arynes form the phosphonium salts, which in the presence of a carbonate base generates the aryl anion equivalent. Subsequent addition of the aryl anions with aldehydes afforded the secondary alcohols.

  芳烃是高反应性的中间体，可用于各种X–H键（X = O，N，S等）的亲电芳基化。本文中，证明了一种新的合成策略，其中通过用膦和碱处理将芳烃转化为芳基阴离子当量。将膦类添加到芳烃中形成form盐，其在碳酸酯碱的存在下产生芳基阴离子当量。随后将芳基阴离子与醛加成，得到仲醇。

  An unprecedented palladium-catalyzed allylic alkylation of pronucleophiles with unactivated skipped enynes has been developed. This method provides a straightforward access to a wide array of 1,3-dienes without the need to preinstall leaving groups or employ extra oxidants. The reaction exhibited high atom economy, good functional group tolerance, excellent regioselectivities, and scalability. With

  We report herein a synthesis of quinoxalin‐2(1H)‐ones from 3‐hydroxyindolin‐2‐one derivatives, which can be synthesized from commercially available isatins in one or two steps. The reaction proceeded through a CF₃CO₂H‐mediated azidation via a carbocation, followed by acid‐induced N₂ extrusion and ring‐expansion. Both CF₃CO₂H and the solvent 1,1,1,3,3,3‐hexafluoro‐2‐propanol were found to be crucial for this rearrangement. The axial chirality in 3‐hydroxyindolin‐2‐one skeleton was fully preserved in the products.

  摘要 我们在此报告了一种从 3-羟基吲哚啉-2-酮衍生物合成喹喔啉-2(1H)-酮的方法。该反应是通过一个碳位化合物在 CF3CO2H 介导下发生叠氮反应，然后在酸的诱导下发生 N2 挤压和扩环反应。研究发现，CF3CO2H 和溶剂 1,1,1,3,3,3-六氟-2-丙醇对这一重排反应至关重要。产物中完全保留了 3-hydroxyindolin-2-one 骨架的轴向手性。

  The present invention provides compounds and methods of administering compounds to a subject that can reduce βAPP production and that is not toxic in a wide range of dosages. The present invention also provides non-carbamate compounds and methods of administering such compounds to a subject that can reduce βAPP production and that is not toxic in a wide range of dosages. It has been discovered that either the racemic or enantiomerically pure non-carbamate compounds can be used to decrease βAPP production.
