METHOD OF PRODUCING N-ALKYL-N,N-BIS[Ω-(PIPERIDIN-1-YL)ALKADIIN-1-YL]AMINES EXHIBITING FUNGICIDAL ACTIVITY Russian patent published in 2020 - IPC C07D211/26 A01N43/40 

FIELD: chemistry.

SUBSTANCE: invention relates to N-alkyl-N,N-bis[ω(piperidin-1-yl) alkadiin-1-yl] amines of formula (1), a method for production thereof and use as an agent with fungicidal activity on fungi Bipolaris sorokiniana and Rhizoctonia solani. Method comprises reacting N-alkyl-substituted 1,5,3-dioxazepanes of general formula RN(CH₂OCH₂)₂, where R = n-Bu, iso-Pr, with α,ω-diacetylenes in the presence of a CuCl catalyst taken in molar ratio of N-alkyl-substituted 1,5,3-dioxazepane: α,ω-diacetylene: CuCl = 1:2:0.05 in an argon atmosphere at temperature of 80 °C and atmospheric pressure in toluene as solvent for 6 hours with subsequent addition to the reaction mass of paraform, piperidine and CuCl, taken in molar ratio of 2:2:(0.03-0.07) and stirring the reaction mass for 6 hours at temperature 80 °C.

EFFECT: compounds of general formula (1) can be used as precursors for fine organic synthesis and biologically active compounds.
