  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.

  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

  An ylide-based aza-Payne rearrangement of 2,3-aziridin- 1 -ols leads to an efficient process for the preparation of pyrrolidines. The aza-Payne rearrangement under the basic reaction conditions favors the formation of epoxy amines. Subsequent nucleophilic attack of the epoxide by the ylide yields a bis-anion, which upon a 5-exo-tet ring closure yields the desired pyrrolidine, thus completing the relay of the 3-membered the 5-membered nitrogen containing ring system. This process takes place with complete transfer of stereochemical fidelity, and can be applied to sterically hindered aziridinols.

  基于叶立德的2,3-氮杂环丙醇的aza-Payne重排反应导致了一种高效的吡咯烷制备过程。在碱性反应条件下进行的aza-Payne重排有利于环氧胺的形成。叶立德对环氧化物的亲核攻击产生双阴离子，随后通过5-内攻环闭合产生所需的吡咯烷，从而完成了含3-成员和5-成员氮环的环的传递。这个过程完全保持立体化学的保真度，并可应用于立体位阻的氮杂环丙醇。
