  • Synthesis and Cycloaddition Reactions of Stabilized Münchnones
    作者:Taban K. K. Kakaawla、Will C. Hartley、Joseph P. A. Harrity
    DOI:10.1002/ejoc.201600486
    日期:2016.6
    A family of stabilized munchnones bearing an acyl group at C4 have been prepared and studied in alkyne cycloaddition reactions. These reactions are highly regioselective, and the method represents a rapid and straightforward route to densely substituted pyrroles. Finally, the C4-stabilizing units can be further manipulated to furnish carboxylic acid and amide groups, or removed altogether to provide
    已经制备并在炔环加成反应中研究了一系列在 C4 处带有酰基的稳定 munchnones。这些反应具有高度的区域选择性,该方法代表了一种快速而直接的制备高密度吡咯的途径。最后,可以进一步操纵 C4 稳定单元以提供羧酸和酰胺基团,或完全去除以提供未取代的吡咯
  • Convenient Synthesis of 4-Trifluoromethyl-Substituted Imidazole Derivatives.

    Mesoionic 4-trifluoroacetyl-1, 3-oxazolium-5-olates (1), obtained from the reaction of N-acyl-N-alkylglycines (2) with trifluoroacetic anhydride, react with ammonia to give 4-trifluoromethyl-3, 4-dihydroimidazoles (3) in high yields. Dehydration of 3 gives 4-trifluoromethylimidazoles (4) in high yields. The novel ring transformation of 1 into 3 occurs via a regioselective attack of ammonia on the C-2 position of the ring.
    美索离子4-三氟乙酰基-1,3-噁唑啉-5-醇盐(1)是由N-酰基-N-烷基甘酸(2)与三氟乙酸酐反应得到的,能够与反应生成4-三甲基-3,4-二氢咪唑(3),产率高。3的脱反应高产率地生成4-三甲基咪唑(4)。1到3的这一新颖环转换过程是通过对环C-2位点的区域选择性攻击实现的。

    Mesoionic 4-trifluoroacetyl-1, 3-oxazolium-5-olates (1), obtained from the reaction of N-acyl-N-alkylglycines (2) with trifluoroacetic anhydride, react with amidines to give 5-trifluoroacetylimidazoles (3) in moderate yield. The novel ring trandformations of 1 into 3 occur via an initial attack of amidines on the C-2 position of the ring.
