PROCESS FOR THE PREPARATION OF 3,3-DIALKYL-7-ARYL-1,2,4,5,7-TETRAOXAZOCANES Russian patent published in 2018 - IPC C07D273/01

Abstract RU 2664647 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a process for the preparation of 3,3-dialkyl-7-aryl-1,2,4,5,7-tetraoxazocanes (1):

R₁=CH₃, R₂=C₆H₁₃, R=m-Cl, m-F, p-Cl; R₁=C₄H₈, R₂=C₄H₉, R=m-Cl, p-Cl; R₁=C₂H₄, R₂=C₄H₉, R=m-Cl, p-F, in which m-, p-halogenoanilines are reacted with 3,3-dialkyl-1,2,4,5,7-pentaoxacanes in the presence of Sm(NO₃)₃⋅6H₂O at the molar ratio aniline : 3,3-dialkyl-1,2,4,5,7-pentaoxacane : Sm(NO₃)₃⋅6H₂O = 10 : (10–12) : (0.3–0.7) at room temperature (20 °C) and atmospheric pressure for 4–6 hours in tetrahydrofuran.

EFFECT: method for the preparation of 3,3-dialkyl-7-aryl-1,2,4,5,7-tetraoxazocanes (1) in a high yield is proposed.
