FIELD: technological processes.
SUBSTANCE: invention relates to a method for producing polyfunctional O- and S-containing macroheterocycles, which have a wide potential as: bioactive preparations, insecticides, and noble extractants.
EFFECT: method has been developed for producing O- and S-containing macroheterocycles, which consists in catalytic interaction of ethyl-2-diazo-3-oxobutyrate with 1,3-dithian in benzene as a solvent in the presence of copper (II) triflate Cu(OTf)2 at 80 °C for 4 hours, which allows you to increase the yield of the target product.
