应用
2,6-Di-tert-butyl-4-methylpyridine is used for the generation of enol triflates from ketones using trifluoromethanesulfonic anhydride. It is also used in the synthesis of 1,2-dihydro-2-silanaphthalene derivatives, as base in PtCl4-catalyzed cyclization reactions of homopropargyl azide derivatives and in diastereoselective synthesis of β-thiomannopyranosides. 备注
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Recommended storage temperature is 2 - 8?°C. Store under inert gas. It is sensitive to air and light. 基本信息 MDL
