Abstract Addition of substituted benzyl bromides to dialkyl azodicarboxylates under aqueous zinc-mediated addition conditions occurs readily to afford monobenzylated hydrazides in good to excellent yields. The reaction is tolerant of a variety of substituents on the benzyl bromide ring. Several dialkyl azodicarboxylates were successfully tested under the reaction conditions. The limitations of the
摘要 在水性锌介导的加成条件下,取代的苄基溴与偶氮二羧酸二烷基酯的加成很容易发生,以良好到极好的产率提供单苄基酰肼。该反应耐受苄基溴环上的各种取代基。在反应条件下成功测试了几种偶氮二羧酸二烷基酯。还解决了反应的局限性。[本文提供补充材料。访问出版商的 Synthetic Communications® 在线版,获取以下免费补充资源:完整的实验和光谱细节。] 图形摘要
