FIELD: chemistry. ^ SUBSTANCE: invention relates to a method for synthesis of 2,4-cis-8-anti-trialkyl-3-thia-1,5-diazabicyclo[3.2.1]octanes with general formula: The method involves reacting aliphatic aldehyde (acetic, propionic, butyric, valerianic, caproic) saturated with hydrogen sulphide with 1,2-diaminoethane in molar ratio diamine:aldehyde:hydrogen sulphide equal to 1:3:2, at 0C for 3 hours. 2,4-cis-8-anti-trialkyl-3-thia-1,5-diazabicyclo[3.2.1]octanes can be used as selective sorbents and extraction agents of precious metals, as antibacterial, antiviral, fungicidal and acaricidal agents. ^ EFFECT: stereoselective synthesis of one conformationally pure 2,4-cis-8-anti-trialkyl-3-thia-1,5-diazabicyclo[3,2,1]octane isomer; the method is also distinguished by simplicity of carrying experiments and availability of initial reagents. ^ 1 cl, 1 ex, 1 tbl |
