Allgemeine Beschreibung

Methyl trifluoromethanesulfonate (Methyl triflate) is a strong methylating agent. It is also a powerful alkylating agent and a strong irritant.
Shown to be the most effective monomethylating agent in reactions with potassium enolates.
Useful methylation reagent for the conversion of amines to methyl ammonium triflates.

Anwendung

Methyl trifluoromethanesulfonate was used in the synthesis of 2-Benzyloxy-1-methylpyridinium trifluoromethanesulfonate.

This paper describes an improved preparation of [11C]verapamil by reaction of [11C]methyl triflate with desmethylverapamil. The optimal reaction temperature, amount of precursor and reaction time were assessed. With this method [11C]verapamil can be prepared with a reproducible radiochemical yield of

Synthesis of 1-[11C]methylpiperidin-4-yl propionate ([11C]PMP), an in vivo substrate for acetylcholinesterase, is reported. An improved preparation of 4-piperidinyl propionate (PHP), the immediate precursor for radiolabeling, was accomplished in three steps from 4-hydroxypiperidine by (a) protection of the amine as the
