    日期:1995.4
    Fragments of the thiopeptide antibiotic MDL 62,879 (GE2270A) were prepared under mild degradation conditions. Their structures were determined by spectroscopic techniques and by comparison to synthetic reference thiazolyl dipeptides. The two thiazolyl amino acids have stereocenters with S configurations and their sequence is reversed with respect to the structure previously proposed for MDL 62,879

  • Asymmetric multicomponent reactions: convenient access to acyclic stereocenters and functionalized cyclopentenoids
    作者:Arun K. Ghosh、Sarang S. Kulkarni、Chun-Xiao Xu、Khriesto Shurrush
    DOI:10.1016/j.tetasy.2008.04.005
    日期:2008.5
    Asymmetric multicomponent reactions of optically active phenyl dihydrofuran, keto ester or N-tosyl imino ester, and allylsilane provided functionalized phenyl tetrahydrofurans with multiple stereogenic centers diastereoselectively. Cleavage of the resulting substituted tetrahydrofurans readily provided acyclic derivatives with three contiguous asymmetric centers via an acyloxycarbenium ion intermediate. Ring closing olefin metathesis, using Grubbs catalyst, afforded functionalized cyclopentene derivatives in optically active form. A one-pot tandem tetrahydrofuran ring cleavage followed by ring closing olefin metathesis also provided functionalized cyclopentenes in good yield. (C) 2008 Elsevier Ltd. All rights reserved.
