We herein disclose the use of tetramethylammonium fluoride (TMAF) as a direct and selective methylating agent of a variety of amides, indoles, pyrroles, imidazoles, alcohols, and thiols. The method is characterized by operational simplicity, wide scope, and ease of purification. Our computational studies suggest a concerted methylation-deprotonation as the preferred reaction pathway.
我们在此公开了四甲基氟化铵(TMAF)作为各种酰胺,吲哚,吡咯,咪唑,醇和硫醇的直接和选择性甲基化剂的用途。该方法的特点是操作简单,范围广,纯化容易。我们的计算研究表明,一致的甲基化-去质子化是优选的反应途径。
