METHOD FOR PREPARING N-(1,5,3-DITHIAZOCYNAN-3-YL)AMIDES Russian patent published in 2013 - IPC C07D285/38 C07D417/12

Abstract RU 2496777 C2

FIELD: chemistry.

SUBSTANCE: invention refers to organic chemistry, more specifically to a method for preparing N-(1,5,3-dithiazocynan-3-yl)amides of formula , wherein R=p-C₅H₄N (a), (CH₃)₃CO (b), o-CH₃OC₆H₄ (c), which can find application as biologically active compounds, selective sorbents and precious metal extractants. Substance of the method consists in the reaction of N¹,N¹,N⁷,N⁷ - tetramethyl-2,5-dithiaheptane-1,7-diamine with hydrazides RC(O)NHNH₂ in the presence of the catalyst samaric nitrate crystallohydrate Sm(NO₃)₃·6H₂O at temperature 65-75°C for 20-26 h.

EFFECT: what is developed is a method for preparing new high-selectivity N-(1,5,3-dithiazocynan-3-yl)amides.
