A nickel-catalyzed reductivecyclization of enones affords a wide array of indanones in high enantiomeric induction. The reaction is featured with an unprecedented broad scope of substrates. The versatility of the new method is demonstrated in several short stereoselective syntheses of medically valuable (R)-tolterodine, parent and deuterated (+)-indatraline, and an antitumor natural product, (+)-multisianthol

An efficient and regioselective hydrodehalogenation of aromatic α‐ and β‐halo carbonylcompounds has been developed using CuI in isopropanol under basic condition. This reaction system effectively reduces chloride, bromide and iodide groups and affords high yield (up to 97 %) as carbonylcompounds. The method is environmentally friendly and demonstrates excellent tolerance to a broad range of electronically

Chiral boro-phosphates were developed from chiral phosphoric acids and Piers’ borane via the release of H2. A highly enantioselective hydroalkoxylation of 2-vinylbenzyl alcohols was further demonstrated, furnishing optically active 1,3-dihydroisobenzofuran derivatives in high yields with up to 97 % ee. It is supposed that these boro-phosphates possibly interact with the substrates through O−H bond
手性硼磷酸盐是由手性磷酸和 Piers 硼烷通过释放 H 2开发的。进一步证明了 2-乙烯基苄醇的高度对映选择性加氢烷氧基化,以高达 97% 的 ee 的高产率提供光学活性 1,3-二氢异苯并呋喃衍生物。推测这些硼磷酸盐可能通过OH键活化与底物相互作用。
