use | organic synthesis intermediate. a sterically hindered, non-nucleophilic base which distinguishes between Br nsted (protonic) and Lewis acids. Enables the direct high-yield conversion of aldehydes1 and ketones1,2 to vinyl triflates. |
Production method | First, 2, 6-di-tert-butyl-4-methylpyran (trifluoromethanesulfonic acid) salt is prepared from trimethylacetyl chloride, tert-butanol and trifluoromethanesulfonic acid. The salt is then suspended in ethanol and cooled to -60°C to react with concentrated ammonia to produce 2, 6-di-tert-butyl-4-methylpyridine. |
