N,N′-Dimethylpropyleneurea (DMPU) is a cyclic urea sometimes used as a polar, aprotic organic solvent. In 1985, Dieter Seebach showed that it is possible
high thermal and chemical stability. It is a homolog of the related solvent DMPU. It can be prepared from 1,2-dimethylethylenediamine by reaction with phosgene
metal cations. Other alternatives to HMPA include the N,N′-tetraalkylureas DMPU (dimethylpropyleneurea) or DMI (1,3-dimethyl-2-imidazolidinone). Tripyrrolidinophosphoric
(Z)-enolate transition state. Addition of polar additives such as HMPA or DMPU favors the formation of (Z) enolates. The Ireland model argues that these

alkylation of α-branched amide enolates is also possible, though the addition of DMPU is necessary for less reactive electrophiles. Conditions have been developed
