analogue of the pyrrole insecticide pirate, are reported. Acylaminoketone salts were obtained from ketobromides in moderate to high yields and excellent purity. A number of N-tosyl pyrroles were obtained; however, formation of the target acyl tosyl pyrroles was thwarted by the stereoelectronic effects of the pyrrole substituents. During the pyrrole subunit chemistry, an interesting pyrrole derivative,
报告了对吡咯杀虫剂海盗结构独特的吡咯-恶唑类似物的选定类似物的平行合成的研究。从酮溴化物中以中等至高产率和极好的纯度获得酰氨基酮盐。得到许多N-甲苯磺酰基吡咯;然而,吡咯取代基的立体电子效应阻碍了目标酰基甲苯磺酰基吡咯的形成。在吡咯亚基化学过程中,分离出一种有趣的吡咯衍生物乙烯基吡咯。通过限制芳基亚基的多样性,当芳基环上不存在给电子基团或不存在基团时,可以平行合成中等纯度的选定吡咯-恶唑。
