    Catalytic Enantioselective Iodocyclization of γ-Hydroxy-cis-alkenes
    摘要:
    Enantioselective iodocyclization of gamma-hydroxy-cis-alkenes has been achieved using I2 in the presence of an unprecedented catalyst system generated from (R,R)-t-Bu-salen-Co(II) complex and NCS to produce 2-monosubstituted tetrahydrofurans up to 90% ee. While NCS turned out to be the essential additive, neither (R,R)-salen-Co(II) nor (R,R)-salen-Co(III) by itself is likely to be the active species responsible for the asymmetric intramolecular iodoetherification.

  • Asymmetric Iodocyclization Catalyzed by Salen–CrIIICl: Its Synthetic Application to Swainsonine
    作者:Hyo Young Kwon、Chul Min Park、Sung Bae Lee、Joo-Hack Youn、Sung Ho Kang

    The previously developed enantioselective iodocyclization of gamma-hydroxy-cis-alkenes required 30 mol% of (R,R)-salen-Co(II) complex as chiral catalyst and 0.75 equivalent of N-chlorosuccinimide (NCS) as activator to produce 2-substituted tetrahydrofurans with 61 to 90% ee. Due to the considerable loading amount of the Co(II) complex, another more effective catalyst was pursued by screening (R,R)-salen-transition
    先前开发的γ-羟基-顺式烯烃的对映选择性环化需要30摩尔%的(R,R)-salen-Co(II)配合物作为手性催化剂和0.75当量的N-代琥珀酰亚胺NCS)作为活化剂以生产2- ee为61至90%的取代四氢呋喃。由于Co(II)配合物的大量负载,通过筛选(R,R)-salen-过渡属配合物寻求了另一种更有效的催化剂。当10摩尔%的催化剂应用0.5当量的NCS时,相应的Cr(III)Cl(84%ee),Mn(II)Cl(52%ee)和Co(II )配合物(66%ee)。条件的完善建立了一种新的催化对映选择性环化方案,该方案使用在7摩尔%的被0活化的(R,R)-salen-Cr(III)Cl络合物存在下进行。
