- PREPARATION OF 1-AMINOBUTAN-2-OL ENANTIOMERS
-
A method of obtaining enantiomers of 1-amino-butan-2-ol through resolution of racemic 1-N-benzylaminobutan-2-ol with tartaric acid and catalytic debenzylation of the synthesized isomers have been developed.Optical purity of the obtained compounds has been

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