synthesize pyrrolo[2,1,5-cd]indolizinederivatives. The reaction sequence proceeds via preparation of 3-acyl-5-methylindolizines followed by an intramolecularcondensation. The procedures were carried out under convenient conditions and gave the products in high yields. It could be expected to be used to prepare a broad range of potentially interesting pyrrolo[2,1,5-cd]indolizinederivatives.
已经开发了一种有效的两步法来合成吡咯并[2,1,5- cd ]吲哚嗪衍生物。反应序列通过制备3-酰基-5-甲基吲哚并随后进行分子内缩合而进行。该程序在方便的条件下进行,并以高收率得到产物。可以预期将其用于制备范围广泛的潜在有趣的吡咯并[2,1,5- cd ]吲哚嗪衍生物。
