  Stereoconvergent Synthesis of Chiral Allylboronates from an E/Z Mixture of Allylic Aryl Ethers Using a 6-NHC−Cu(I) Catalyst

  摘要：

  We present a 6-NHC-Cu(I) complex that provides alpha-substituted allylboronates using allylic aryl ether substrates. The method was discovered by comparison of the chemoselectivities exhibited by complexes 1a, 1b, 2, and 3. We observed that 1a preferentially reacts with electron-rich alkenes over electron-deficient alkenes. Development of an asymmetric method revealed that 1b reacts with both the E and Z isomers to provide the same absolute configuration without showing E-Z isomerization. This stereoconvergent reaction occurs with high yields (av 86%), high S(N)2` selectivity (> 99:1), and high ee (av 94%) and exhibits wide functional-group tolerance using pure E or Z isomer or E/Z alkene mixtures. The stereoconvergent feature enables the use of many different olefination strategies for substrate production, including cross-metathesis. Chiral allylboronates could be purified by silica gel chromatography and stored in the freezer without decomposition.

  Ir（I）催化的对映选择性脱羧烯丙基醚化：芳基烯丙基醚不对称合成的一般方法

  摘要：

  Ir（I）催化的芳基碳酸烯丙酯的对映选择性脱羧烯丙基醚化反应提供了芳基烯丙基醚。反应的一般性和高立体选择的关键是使用分子内脱羧烯丙基化过程和[Ir（dbcot）Cl] 2作为Ir（I）来源。Ir（I）催化的非对映选择性脱羧烯丙基醚化反应，与不对称醛的crotylation和交叉复分解相结合，可以提供具有高非对映选择性的单保护的2-甲基-1,3-二醇（从简单的醛开始）。

  The yields, enantioselectivities, and regioselectivities of the reactions of amines and phenoxides with allylic carbonates in the presence of a metallacyclic iridium catalyst were compared. These data show that both preactivation of the catalyst and the size of the ligand affect the yield, enantioselectivity, and regioselectivity. With the activated catalyst containing a bis-naphthethylamino group, the allylic amination and etherification of a broad range of allylic carbonates occurred in high yields and with high regioselectivities and enantioselectivities.
