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
