Reaction of 1,1'-Iminobis-2-butanols with Sulfuric Acid

Hernestam, Sven

, p. 1681 - 1685 (2007/10/02)

Treatment of 1,1'-iminobis-2-butanols with 70percent w/w sulfuric acid gives cis- and trans-2,6-diethylmorpholines, 3-ethyl-4-methylpyridine and unsaturated 3-ethyl-4-methylpiperidines.Hydrogenation of the unsaturated 3-ethyl-4-methylpiperidines gives cis- and trans-3-ethyl-4-methylpiperidines.With 50percent w/w sulfuric acid cis- and trans-2,6-diethylmorpholines and a small amount of cis- and trans-2-ethyl-7-methyl-hexahydro-1,4-oyazepines are obtained
