  • Enantioselective iridium-catalyzed carbonyl isoprenylation <i>via</i> alcohol-mediated hydrogen transfer
    作者:Ming Xiang、Guoshun Luo、Yuankai Wang、Michael J. Krische
    DOI:10.1039/c8cc09706b
    日期:——
    Highly enantioselective iridium catalyzed carbonyl (2-vinyl)allylation or "isoprenylation" is achieved via hydrogen auto-transfer or 2-propanol-mediated reductive coupling from primary alcohol or aldehyde reactants, respectively. Using this method, asymmetric total syntheses of the terpenoid natural products (+)-ipsenol and (+)-ipsdienol were achieved.
    高度对映选择性的铱催化的羰基(2-乙烯基)烯丙基化或“异戊烯基化”分别通过氢自转移或2-丙醇介导的伯醇或醛反应物的还原偶联而实现。使用该方法,获得了萜类天然产物(+)-艾酚和(+)-ipsdienol的不对称全部合成。

    (R)-(-)-Ipsdienol 1″ and its antipode 1' were synthesized from (R)-(+)-glyceraldehyde acetonide and (R)-(+)-malic acid, respectively. This established the S-configuration of the naturally occurring (+)-ipsdienol. A new synthesis of (R)-(+)-ipsenol 2″ and its antipode 2' was also described. Chiral epoxides were shown to be useful intermediates for the synthesis of these chiral alcohols.

    The BINOL‐derived chiral phosphoric acid (R)‐TRIP is utilized as an organocatalyst in the asymmetric isoprenylboration reaction of aldehydes, wherein hydrogen‐bond interactions play a key role in the control of enantioselectivity. A wide arrays of enantioenriched dienyl homoallyl alcohols, including two natural products (−)‐Ipsdienol and (−)‐Ipsenol, have been successfully constituted. The synthetic
    BINOL衍生的手性磷酸(R)-TRIP在醛的不对称异戊二烯硼化反应中用作有机催化剂,其中氢键相互作用在控制对映选择性中起关键作用。已经成功地构成了一系列丰富的对映体富集的二烯基均烯丙基醇,包括两种天然产物(-)-伊潘二醇和(-)-伊潘醇。还公开了对手性异戊烯基化的异苯并呋喃酮,乙烯基环氧乙烷和环己烯衍生物的合成应用。
