Abstract
An efficient method for the synthesis of di(6,7,13,14,18,19-hexaoxa-16-azadispiro[4.2.48.75]nonadecan-16-yl)methane(thi)ones and N -substituted hexaoxaazadispiroalkanecarboxamides by the reaction of 3,6-di(spiroalkane)substituted heptaoxacycloundecanes with thiourea and urea derivatives (urea, 1,1-dimethylurea, 1-phenylurea, 1-allylurea) with the participation of Sm(NO3)3·6H2O as a catalyst.
