Electric Literature of 85838-94-4, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 85838-94-4, name is tert-Butyl 5,6-dihydropyridine-1(2H)-carboxylate. This compound has unique chemical properties. The synthetic route is as follows.
General procedure: To a 1 L flask, with a large stir bar, is added tert-butyl 5,6-dihydropyridine-1(2H)-carboxylate (24.15 g, 132 mmol) and DCM (440 mL). The vessel is cooled in an ice/water bath and 3-chloroperoxybenzoic acid (45.5 g, 264 mmol) is added in one portion. After stirring for 30 min at 0 C., the cooling bath was removed and the mixture was allowed to stir for 24 h. To the suspension was added aqueous sodium metabisulfite (10%, 200 mL), water (100 mL) and DCM (200 mL) and was then stirred vigorously for 10 min. The organic layer is separated, washed with aqueous 1 N NaOH (3×200 mL), brine (200 mL), dried over anhydrous Na2SO4, filtered and concentrated in vacuo to yield the title compound.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 85838-94-4, tert-Butyl 5,6-dihydropyridine-1(2H)-carboxylate.
