  • Investigation of the Chemo- and Stereoselectivity of the Ketene-Claisen Rearrangement
    作者:Beat Ernst、Reinhold Oehrlein、Daniel Bellu?、Jozef Gonda、Rainer Jeschke、Udo Nubbemeyer
    DOI:10.1002/hlca.19970800321
    日期:1997.5.12
    A novel type of ketene-Claisen rearrangement in which the precursor of the rearrangement is generated in situ by reaction of optically active allyl thioethers with dichloroketene is described. A characteristic feature of this rearrangement is the excellent chemoselectivity in favor of allyl thioethers vs. allyl ethers, i.e., exclusive chirality transfer of the allylic sulfur moiety is observed with
    描述了一种新型的烯酮-克莱森重排,其中通过光学活性的烯丙基醚与二烯酮的反应原位产生重排的前体。这种重排的特征是相对于烯丙基醚而言,有利于烯丙基醚的出色的化学选择性,即在12、13和25--27处观察到烯丙基部分的手性转移。环状光学活性烯丙基醚(+)-(R)-4和(-)-(S)-4和开链烯丙基醚11--13重排,原位生成的二氯乙烯酮分别形成旋光的酯(-)-(S)-28,(+)-(R)-28和31-33。在循环情况(+)-(R)-4和(-)-(S)-4中,手性转移> 99%,在开链情况11--13中观察到96--98%。此外,二氯乙烯烯-克莱森重排的特征在于高的不对称1,2-诱导。手性烯丙基硫化物25--27得到旋光的酯36--38 通过NMR位移实验测得的1,2-诱导> 99%。
  • Ether-directed diastereoselectivity in catalysed Overman rearrangement: comparative studies of metal catalysts
    作者:Ieva Jaunzeme、Aigars Jirgensons
    DOI:10.1016/j.tet.2008.03.099
    日期:2008.6
    Ether-directed diastereoselectivity in Overman rearrangement of delta-methoxy and delta-TBDMSO substituted allylic trichloroacetimidates has been explored using PtCl2, PtCl4, AuCl and AuCl3 catalysts in comparison with commonly used Pd(II) catalysts. For both substrates the use of PtCl2 catalyst gave notably improved anti/syn-ratio of 1,2-aminoalcohol derivatives (anti/syn=11:1 for 5-methoxy; 6:1 for delta-TBDMSO) compared to all metal catalysts known to promote Overman rearrangement. Formation of 2-trichloromethyloxazoline was observed as a dominant side reaction in the metal catalysed rearrangement of a-methoxy substituted allylic trichloroacetimidates considerably reducing the yield of the desired product. This side reaction was suppressed when delta-TBDMS-ether was used as a directing group. (C) 2008 Elsevier Ltd. All rights reserved.
