Description
General description
2,6-Di-tert-butyl-4-methylpyridine is a sterically hindered, non-nucleophilic base which distinguishes between BrÖnsted (protonic) and Lewis acids. It also enables the direct high-yield conversion of aldehydes and ketones to vinyl triflates. It inhibits desilylation and hydration of the products during GaCl₃-catalyzed ortho-ethynylation of phenol.
Application
2,6-Di-tert-butyl-4-methylpyridine has been used:
in the synthesis of 1,2-dihydro-2-silanaphthalene derivatives
as base in PtCl₄-catalyzed cyclization reactions of homopropargyl azide derivatives
diastereoselective synthesis of β-thiomannopyranosides
