Electrochemical dimerization of phenacyl bromides N-acylhydrazones—a new way to 1-N-acylamino-2,5-diaryl-pyrroles
摘要:
Cathodic reduction of phenacyl bromides N-acyl hydrazones lead to dimeric 1,4-diaryl-1,4-butanedione di-N-acylhydrazones, which give the corresponding 1-N-acylaniino-2,5-diarylpyrroles in good yields. (C) 2004 Published by Elsevier Ltd.

In the presence of Na2CO3, the conjugate addition between α-halogeno hydrazones and nitroso compounds proceeded readily, thus delivering multifunctionalized nitrones in the reasonable chemical yields with excellent strereoselectivities. The chemical structure and stereochemical configuration of title chemical entities were unambiguously identified by an X-ray single crystal structure analysis.
在 Na2CO3 存在下,α-卤代腙和亚硝基化合物之间的共轭加成很容易进行,从而以合理的化学产率提供具有优异立体选择性的多功能化硝酮。标题化学实体的化学结构和立体化学构型通过 X 射线单晶结构分析明确确定。
