    A Novel [3+2] Cycloaddition Approach to Nitrogen Heterocycles via Phosphine-Catalyzed Reactions of 2,3-Butadienoates or 2-Butynoates and Dimethyl Acetylenedicarboxylate with Imines:  A Convenient Synthesis of Pentabromopseudilin
    摘要:
    The reactivity of a new three carbon synthon, generated in situ from the reaction of 2,3-butadienoates or 2-butynoates with an appropriate phosphine as the catalyst, toward the electron deficient imines is described. Triphenylphosphine-catalyzed reaction of-methyl a,3-butadienoate with N-sulfonylimines gave the single [3+2] cycloadduct in excellent yield; tributylphosphine-catalyzed reaction of methyl 2,3-butadienoate or 2-butynoate with N-tosylimines afforded the corresponding [3+2] cycloadduct as the major product along with a small amount of the three components adduct. Aliphatic N-tosylimines gave moderate yield for this reaction. In addition, a new phosphine-catalyzed cyclization reaction of dimethyl acetylenedicarboxylate with N-tosylimines is also described. A:reaction mechanism is proposed. Further elaborations of the cycloaddition products and the synthesis of pentabromopseudilin using this method are exemplified.

    摘要:
    已经研究了使用重氮化合物的亚胺叠氮和催化量的金属盐和硫化物。一系列具有吸电子基团的苯甲醛衍生的亚胺(N -Ts,N -SO 2 CH 2 CH 2 SiMe 3(SES),N -P(O)Ph 2,N -CO 2 Bn,N -CO 2卜吨,ñ -CO 2(CH 2)2森达3,ñ -CO 2 C(CH 3)制备2 CCl 3),并使用Me 2 S和苯基重氮甲烷在叠氮化过程中进行测试。所有亚胺均获得高产,但非对映选择性差异很大(3:1–> 10:1)。用化学计量的硫化物测试了一系列N -SES亚胺,芳族和脂族亚胺均获得了高收率。随后用化学计量和亚化学计量的对映体纯的1,3-氧杂蒽3与Rh 2(OAc) 4和Cu(acac) 2来测试这些亚胺。Rh 2(OAc) 4的收率高,对映选择性高(89–95%),尽管使用Cu(acac)2(85-95%)观察到对映体过量有小幅减少,尤其是当使用亚化学计量的

  • Highly Diastereoselective Aziridination of Imines with Trimethylsilyldiazomethane. Subsequent Silyl Substitution with Electrophiles, Ring Opening, and Metalation of <i>C</i>-SilylaziridinesA Cornucopia of Highly Selective Transformations

    C-silylaziridines was investigated. Treatment with F(-) (tetrabutylammonium triphenyldifluorosilicate was used) in the presence of aldehydes gave the alpha-hydroxyaziridines in high yield and high diastereoselectivity (86:14-98:2) for the newly created stereogenic center. Complete retention of configuration was observed in the substitution of the silyl group with electrophiles in all cases. Trapping with deuterium

  • A highly diastereoselective synthesis of 3-carbethoxy-2,5-disubstituted-3-pyrrolines by phosphine catalysis
    作者:Xue-Feng Zhu、Christopher E. Henry、Ohyun Kwon
    DOI:10.1016/j.tet.2005.03.104
    日期:2005.6
    Tributylphosphine was used as catalyst to facilitate a [3+2] cycloaddition between gamma-substituted allenoates and N-sulfonylimines. The resulting adducts, 3-carbethoxy-2,5-disubstituted-3-pyrrolines were formed in excellent yields with high diastereoselectivity. The reaction went to completion in several hours at room temperature, and the starting materials were easily prepared with one step from commercially available compounds via known procedures.
