摘要

The new uronium salts O-succinimidyl-1, 3-dimethyl-1, 3-trimethyleneuronium hexafluorophosphate (HSDU) and tetrafluoroborate (TSDU) have been prepared from 1, 3- dimethylpropyleneurea (DMPU) and employed in the synthesis of N-hydroxysuccinimide- derived active esters. High yields were obtained at room temperature in short reaction times and no racemization was observed.
