Ironing it out: The straightforward N‐alkylation using alcohols and iron/amino acid catalysis is described (see scheme). The reaction does not proceed by the conventional “borrowing hydrogen” mechanism, but appears to involve a substitution pathway (SN) at the sp3 carbon atom bearing the hydroxy group of the alcohol. Developing a catalyst that is effective at a near neutral pH was key to the successful
解决:描述了使用醇和铁/氨基酸催化的简单N-烷基化反应(参见方案)。该反应不是通过常规的“借入氢”机理进行的,而是似乎在带有醇羟基的sp 3碳原子上涉及一个取代途径(S N)。开发一种在接近中性pH值时有效的催化剂是成功进行N烷基化的关键。
