The asymmetric totalsyntheses of deshydroxytetramethylcupressuflavone and desmethylkotanin and the synthesis of a key intermediate in the previous synthesis of hibarimicinone are described using an axially chiral biarylboronic acid, prepared by the diastereomeric resolution of the corresponding rac‐boronic acid, as a common intermediate. Conversion of the boronic acid moiety into either a hydrogen
A new protocol for the enantioselective synthesis of 3,3′-disubstituted-1,1′-bi-6-methoxy-2-phenol (BIPhOL) derivatives is described. Diastereomeric resolution of racemic BIPhOL boronic acid using a boronic acid moiety as a resolving group generated two diastereomers and subsequent Suzuki-Miyaura coupling reaction of the resulting diastereomers with aryl halides provided BIPhOL derivatives without

Efficient access to chiral C(sp3) boronates in stereochemically pure form is critical for realizing the substantial potential of such buildingblocks in complex-molecule synthesis. We herein report that a pinene-derived iminodiacetic acid (PIDA) ligand enables the highly diastereoselective synthesis of a wide range of oxiranyl C(sp3) boronates from the corresponding olefins. These oxiranyl PIDA boronates
有效获取立体化学纯形式的手性 C(sp3) 硼酸酯对于实现此类构建块在复杂分子合成中的巨大潜力至关重要。我们在此报告蒎烯衍生的亚氨基二乙酸 (PIDA) 配体能够从相应的烯烃中高度非对映选择性地合成各种环氧乙烷基 C(sp3) 硼酸酯。反过来,这些环氧乙烷基 PIDA 硼酸酯可以通过硼酸酯基团的新型 1,2-迁移很容易地转化为前所未有的稳定的 α-硼醛,该迁移可以完全保持立体化学纯度。含有双 sp3 杂化 C 中心的 B 保护卤硼酸可通过该平台轻松访问,

manner. Racemic BINOL boronic acid reacted with a commercially available pinene-derived iminodiacetic acid as a chiralboron ligand to generate the two diastereomers in quantitative yields over a gram-scale quantity. After the removal of the chiralboron ligand from the diastereomers under mild conditions, the subsequent Suzuki coupling reaction of the resulting chiral BINOL boronic acids with aryl halides
