    A Straightforward Synthesis of Tetrameric Estrone-Based Macrocycles
    摘要:
    A straightforward approach to macrocycles having four estrone-derived nuclei by the sequential Cu-catalyzed Huisgen azide-alkyne cycloaddition-Glaser-Eglington Cu homocoupling has been developed. Due to its efficiency and simplicity, this sequence is useful for application to different natural product scaffolds.

  • Asymmetric synthesis of unsaturated and bis-hydroxylated (S,S)-2,7-Diaminosuberic acid derivatives
    作者:Peter Kremminger、Kjell Undheim
    DOI:10.1016/s0040-4020(97)00393-1
    日期:1997.5
    Stereoselective syntheses of cystine substitutes with all-carbon C4-bridges are described. The disulfide unit between the two alanine moieties in cystine has been replaced by a C2-unit. When the C2-unit is olefinic, conformationally constrained cis- and trans-unsaturated analogues result. Vicinal dihydroxy analogues were formed when the C2-unit was a vicinal 1,2-ethylenediol derivative. N-Fmoc protection

    Enantiomerically pure dithiolene complexes NBu4[Ni[(R,R)-diotte)2] and NBu4[Ni((S,S)-diotte]2] (diotte2- = a 1,3-dioxolane-tetrathiaethylene), were prepared from the corresponding enantiomers of a diotte2- precursor. The structure of the precursor was solved by single-crystal X-ray analysis; desulfurization afforded a novel tetrathiafulvalene derivative. Combination of the complex monoanion with the enantiomers

H距离(2.77至2.86 A)的阳离子-阴离子相互作用,以及短距离的S-H阴离子-阴离子相互作用。 .S距离为3.55至3.65A。在没有叠层内相互作用的情况下,在该络合物和其他络合物中均未检测到离子对电荷转移带。ESR和UV / Vis数据表明,在[Ni(diotte)2]-中,电子离域作用不如相应的mnt2-和dmit2-配合物中明显。压制粉末药丸的比电导率(sigma)为10(-2)至10(-12)ohm(-1)cm(-1),并且在所有情况下均随温度(293-393 K)的增
  • Asymmetric Synthesis of 2-(α-Aminoalkyl)oxazoles, 2-Oxazolylpyrrolidines, 2-Oxazolylpiperidines: Total Synthesis of 4,5-Dihydroxypipecolinic Acid
    作者:Marion Thieme、Eric Vieira、Jürgen Liebscher
    DOI:10.1055/s-2000-8719
    日期:——
    Asymmetric α-alkylation of 2-aminomethyl-4,5-diphenyloxazole was achieved by formation of azomethines 1 and ent-1 with the enantiomers of 2-hydroxypinan-3-one as chiral auxiliaries, reaction with alkylating reagents and final removal of the chiral auxiliary giving rise to optically active 2-(α-aminoalkyl)oxazoles 3, ent-3, 6 and 9. If α,ω-dihaloalkanes were used the resulting alkylation products could be further cyclized by intramolecular alkylation of the amino group to afford optically active 2-oxazolyl-N-heterocycles 4, ent-4, 7 and 10. The latter could be used for the total synthesis of naturally occurring 4,5-dihydroxypipecolinic acid 13.
