  • New Preparation of 2-N-Alkyl(aryl)amino-5-methyl-4H-1,3-thiazin-4-ones and 3,4-Dihydro-5-methyl-2,4-dioxo-2H-1,3-thiazine
    作者:Dušan Koščík、Milan Dzurilla、Peter Kutschy

    日期:——

    Addition-cyclization reactions of 3-bromo- and 3-chloro-2-methylpropenoylisothiocyanates with primary and secondary amines and alcohols have been studied. The formed addition products, thioureas, underwent cyclization of heating with ethanolic KOH or in dimethylformamide in the presence of lithium hydride. This method represents a new approach to 2-dialkyl(aryl)amino-5-methyl-4H-1,3-thiazin-4-ones. Addition reactions with alcohols afforded 3,4-dihydro-5-methyl-2,4-dioxo-2H-1,3-thiazine as the sole product. The structure of the synthesized compounds was confirmed by 1H NMR, 13C NMR, IR and mass spectroscopy.

  • Total Synthesis of Lucilactaene, A Cell Cycle Inhibitor Active in p53-Inactive Cells
    作者:Robert S. Coleman、Matthew C. Walczak、Erica L. Campbell
    DOI:10.1021/ja056217g
    日期:2005.11.23
    Hetero-bis-metalated 1,3-butadiene is employed in the lynchpin coupling of synthetic fragments of the side chain of the antitumor agent, lucilactaene. Sequential Stille and Suzuki-Miyaura couplings interpolate this unique boron/tin diene into the pentaene chain. The total synthesis of lucilactaene was accomplished efficiently, in just eight linear steps.
  • Enantioselective Radical Addition/Trapping Reactions with α,β-Disubstituted Unsaturated Imides. Synthesis of <i>a</i><i>nti</i>-Propionate Aldols
    作者:Mukund P. Sibi、Goran Petrovic、Jake Zimmerman
    DOI:10.1021/ja043371e
    日期:2005.3.1
    This manuscript describes a highly diastereo- and enantioselective intermolecular radical addition/hydrogen atom transfer to alpha,beta-disubstituted enoates. Additionally, we show that anti-propionate aldol-like products can be easily prepared from alpha-methyl-beta-acyloxyenoates in good yields and high diastereo- and enantioselectivities.
