Abstract
The ^1^H and ^13^C NMR spectroscopic data for alkyl and polyamine‐linked bis(2‐thioxo‐[1,3,5]thiadiazinan‐3‐yl) carboxylic acids, prepared from alkyl diamines and N^4^‐(benzyl) spermidine have been fully assigned by combination of one‐ and two‐dimensional experiments (DEPT, HMBC, HMQC, COSY).
