  Synthesis of optically active cis- and trans-1,2-disubstituted cyclopropane derivatives by the Simmons-Smith reaction of allyl alcohol derivatives derived from (R)-2,3-O-isopropylideneglyceraldehyde

  摘要：

  The Simmons-Smith reactions of Z- and E-allyl alcohol derivatives 6 derived from (R)-2,3-O-isopropylideneglyceraldehyde (5) were used for the synthesis of optically active cis- and trans-1,2 disubstituted cyclopropane derivatives. Reaction of 6 with diethyl zinc and diiodomethane gave cyclopropane derivatives 7 in 84% to quantitative yields with 35 to approximate to 100% des. Identical facial selectivities toward the double bonds, Ire-asi for Z-6 and 1re-2re for E-6, were observed in the cyclopropanations. The diastereoselectivity was dependent on the protecting group on the terminal allylic oxygen (R of 6, TBDPS > MOM > Bn) and on the stereochemistry of the double bond (Z > E). For TBDPS ethers Z- and E-6c, cis- and trans-7c were obtained as single diastereomers respectively. It was clearly demonstrated that the stereoselectivity of the cyclopropanation is controlled by the directing effect of the allylic oxygen (O-1) of the dioxolane ring which coordinates to the reagent. The terminal allylic oxygen (O-2) lowered the diastereoselectivity This reaction was applied to the synthesis of optically active cyclopropane analogs of gamma-aminobutyric acid (GABA) 18, 22, and ent-22.

• Sterically Demanding Oxidative Amidation of α-Substituted Malononitriles with Amines Using O₂
  作者：Jing Li、Martin J. Lear、Yujiro Hayashi

  DOI：10.1002/anie.201603399

  日期：2016.7.25

  An efficient amidation method between readily available 1,1-dicyanoalkanes and either chiral or nonchiral amines was realized simply with molecular oxygen and a carbonate base. This oxidative protocol can be applied to both sterically and electronically challenging substrates in a highly chemoselective, practical, and rapid manner. The use of cyclopropyl and thioether substrates support the radical

  简单地使用分子氧和碳酸盐碱即可实现易于获得的1,1-二氰基烷烃与手性或非手性胺之间的高效酰胺化方法。该氧化方案可以高度化学选择性，实用和快速的方式应用于空间和电子挑战性底物。环丙基和硫醚底物的使用可支持α-过氧丙二腈物种的自由基形成，后者可以环化成二恶英，后者可以单价氧化丙二腈α-碳二酮以提供能够与胺亲核试剂反应的活化的酰基氰化物。

  A Rh-catalysed [5 + 1] cycloaddition of allenylcyclopropanes and CO has been developed to synthesize functionalized 2-methylidene-3,4-cyclohexenones. The scope of this methodology has been investigated, showing that various functional groups can be tolerated. Both di- and tri-substituted allenylcyclopropanes can be applied to this cycloaddition and the [5 + 1] cycloadducts with the E configuration
