Use of Tetrahydro-2H-1,3-Oxazinones as Aminopropylation Agents
摘要:
Treatment of tetrahydro-2H-1,3-oxazin-2-one (1) or the 3-methyl derivative 2 with aniline salts or thiophenols at 180-degrees-C affords the corresponding N-aryl-1,3-propanediamines 3 or 3-(arylthio)propanamines 4 in good yields.
A method for producing a cyclic carbamate ester produces the cyclic carbamate ester by reacting an organic compound having at least two halogen atoms per molecule, an amine having at least two hydrogen atoms on a nitrogen atom, and carbon dioxide.
