only: An atom‐economical synthetic route towards arylated Z‐enamides through double CH functionalization is described. The Z/E selectivity of the palladium‐catalyzed monoarylation is absolute (step A in scheme), and the molecular complexity of the products can be further endowed by a sequential second arylation, which requires the use of trifluoracetic acid (TFA; step B).
仅Z:描述了通过双CH官能化制取芳基化Z-
酰胺的原子经济合成路线。
钯催化的单芳基化反应的Z / E选择性是绝对的(方案中的步骤A),并且连续的第二芳基化可以进一步提高产物的分子复杂性,这需要使用
三氟乙酸(T
FA;步骤B) 。
