METHOD OF PRODUCING 10-ARYL-7,8,12,13-TETRAOXA-10-AZA-SPIRO[5,7]TRIDECANES Russian patent published in 2016 - IPC C07D273/01

Abstract RU 2584950 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 10-aryl-7,8,12,13-tetraoxa-10-aza-spiro[5.7]tridecanes of general formula (1): wherein anilines (aniline, o-,m-methylaniline, m-nitroaniline, o-,m-,n-chloroaniline, o-,m-,n-fluoroaniline, o-,m-,n-bromoaniline) is reacted with 7,8,10,12,13-pentaoxsaspiro[5,7]tridecane in presence of a catalyst Sm(NO₃)₃·6H₂O at molar ratio of aniline: 7,8,10,12,13-pentaoxaspiro[5.7]tridecane: Sm(NO₃)₃·6H₂O = 10:(10-12):(0.5-0.7) at room temperature (20 °C) and atmospheric pressure for 20-40 minutes in methylene chloride.

EFFECT: technical result is obtaining 10-aryl-7,8,12,13-tetraoxa-10-aza-spiro[5,7]tridecanes with high output.
