give 1,4- and 1,2-double addition products, and their subsequent transformations afforded multisubstituted pyrroles in good yields. Application of this procedure to the synthesis of an imidazole glycerol phosphate dehydratase inhibitor (IGPDI), a physiologically active 2,3,5-trisubstituted pyrrole, is also described.
二烷氧基乙烯酮甲硅烷基缩醛的双亲核加成反应与 α, β-不饱和亚胺一起进行,得到 1,4- 和 1,2- 双加成产物,它们随后的转化以良好的收率提供了多取代的吡咯。还描述了该程序在合成咪唑甘油磷酸脱水酶抑制剂 (IGPDI)、生理活性 2,3,5-三取代吡咯中的应用。
