short synthesis of some fused indole-heterocycles has been achieved via Pd-catalyzed cross-coupling reactions between azido-2-bromobenzene and arylboronic acids and subsequent thermally induced nitrene insertion. Additionally, 4-amino-α-carboline, a versatile intermediate toward grossularine analogs has also been prepared by Suzuki–Miyaura cross-coupling of 4-pivaloylaminopyridine-3-boronic acid with
通过叠氮基-2-溴苯与芳基硼酸之间的钯催化的交叉偶联反应以及随后的热诱导的腈插入,已经实现了一些稠合的吲哚杂环的短合成。此外,还通过Suzuki-Miyaura将4-新戊酰氨基吡啶3-硼酸与2-溴苯胺交叉偶联,然后进行简单的官能团转化,制备了一种通用的通向小卵磷脂类似物的中间体4-氨基-α-咔啉。
