Ruthenium-catalyzed synthesis of substituted 2-hydroxymorpholines and substituted morpholines
摘要:
The reaction of primary amines with peroxides afforded substituted hydroxymorpholines which were then converted to substituted morpholines via dihydrooxazines as intermediates. The reaction appears to proceed through a ruthenium-catalyzed dehydrogenation-cyclization process.
This invention relates to the reaction of N-alkyl-bis-(2-hydroxyalkyl)amines to form oxazine derivatives by a process comprising reacting said amines in the presence of a ruthenium-containing compound and hydrogen acceptor.
