  • Rearrangement of α-hydroxy imines to α-amino ketones: Mechanistic aspects and synthetic applications
    作者:Philippe Compain、Jacques Goré、Jean-Michel Vatèle
    DOI:10.1016/0040-4020(96)00317-1
    日期:1996.5
    In refluxing diglyme, rearrangement of α-hydroxy imines bearing diversely substituted allyl groups or a 3-trimethylsilylpropargyl group on the α-carbon to the nitrogen afforded in good yields α-amino ketones. Migration of allyl or 3-trimethylsilylallyl groups occured without allylic transposition in contrast to the 1-methylallyl group. In the 3 cases studied, the rearrangement of enantioenriched α-hydroxy
    在回流二甘醇二甲醚中,在α-碳上带有不同取代的烯丙基或3-三甲基甲硅烷基炔丙基的α-羟基亚胺重排至氮,可得到高产率的α-氨基酮。与1-甲基烯丙基相比,烯丙基或3-三甲基甲硅烷基烯丙基的迁移没有烯丙基移位而发生。在所研究的3个案例中,对映体富集的α-羟基亚胺发生了完全的1,2-手性转移。重排用于制备(+)-1-苄基-1-氮杂螺[5.5]十一烷-7-one,其是(-)-过氢组蛋白毒素合成中的前体。

    pargyl)-2-hydroxycyclohexanone were respectively obtained by resolution from the corresponding diastereomeric acetal derived from C2-symmetrical diol or from the camphanate ester. Study of the rearrangement of their corresponding imine derivatives has shown that it occurred with complete retention of the stereogenicity.
    通过拆分,分别从衍生自C 2对称二醇或樟脑酸酯的相应非对映体缩醛中获得了对映体富集的2-烯丙基-和2-(3-三甲基甲硅烷基炔丙基)-2-羟基环己酮。对它们相应的亚胺衍生物的重排的研究表明,它的发生完全保留了立体性。
  • Chiral acetals in organic synthesis: Regioselective synthesis of 2-and 3-hydroxy acetals from 2,3-olefinic acetals. Reinvestigation and further applications

    DOI:10.1016/s0040-4020(01)85714-8
    日期:1994.1
    Achiral as well as chiral 2,3-olefinic acetals are converted into 2- and 3- hydroxy acetals via LAH reduction of the corresponding epoxides and via bromohydrins followed by TBTH reductions respectively. Synthesis of 1,3-diones is described. Compounds from chiral systems are further utilized for asymmetric synthesis.

    amino ketone 12. However, the reaction of 2-chlorophenyllithium did not work in which this route was unavailable for the synthesis of 1. Then, an alternative strategy directed toward 1, starting with a compound having 2-chlorophenyl groups in advance, was designed in which the chiral quaternary carbon center bearing a nitrogen atom in the ring is created by the enantioselective reduction of the atropisomeric
    关于麻醉剂(S)-氯胺酮1的不对称合成,进行了与环己烷环中的羰基相邻的氮取代的季碳中心的对映选择性结构。苯基锂与在α-羰基官能团上带有手性助剂的α-酮肟-乙缩醛9的非对映选择性亲核1,2-加成反应,生成的苄氧基胺11主要产率为83%,de为82%,转化为相应的氨基酮12。然而,2-氯苯基锂的反应不起作用,其中该路线不可用于合成1。然后,针对1的替代策略从预先具有2-氯苯基基团的化合物开始,设计了其中通过在对映异构体中间酮18的对映选择性还原和将氰酸烯丙基酯连续转化为对映体而形成​​在环中带有氮原子的手性季碳中心。异氰酸酯重排,具有完整的1,3-手性转移。根据该策略,通过短路径完成了具有极佳选择性(> 99%ee)的1的第一个不对称合成。
