5-Formyl-2-furylboronic acid reacts cleanly with a range of heteroaryl bromides under SuzukiâMiyaura cross-coupling conditions to produce 2-formyl-5-heteroarylfuran derivatives. Subsequent Wittig olefination reactions afford Ï-conjugated alkeneâpyridylâfuran derivatives.
5-氨基-2-呋喃硼酸与多种杂环芳基溴在铃木-宫浦交叉偶联条件下反应,生成2-氨基-5-杂环芳基呋喃衍生物。随后进行的维蒂格烯烃化反应得到π-共轭烯烃-吡啶-呋喃衍生物。
