Selective Methylation of Amides, N‑Heterocycles, Thiols, and Alcohols with Tetramethylammonium Fluoride
journal contribution
posted on 2019-12-13, 20:05 authored by Hong-Gang Cheng, Maoping Pu, Gourab Kundu, Franziska SchoenebeckWe 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.
