Calculate Digit Verification of CAS Registry Number 5131-37:
(6*5)+(5*1)+(4*3)+(3*1)+(2*3)+(1*7)=63

N,N'-Doacylated imidazolidines and hexahydropyrimidines

Luk'yanov, O. A.,Pokhvisneva, G. V.,Ternikova, T. V.

, p. 1376 - 1380 (2007/10/02)

A method for the preparation of N-monoacyl imidazolidines and hexahydropyrimidines (as hydrochlorides) by interaction of monoacylated derivatives of ethylenediamine and trimethylethylenediamine with chloromethyl methyl ether was developed.Also a method for the preparation of N,N'-diacylimidazolidines and hexahydropyrimidines either by acylation of their monoacyl derivatives or by reaction of the corresponding N,N'-diacyl alkylenediamine derivatives with dimethoxymethane, diacetoxymethane, 1,3,5-trioxane or chloromethyl methyl ether was designed. - Key words: N-mono- and N,N'-diacylated imidazolidines, N-mono- and N,N'-diacylated hexahydropyrimidines, N,N'-diacylated alkylenediamines, acylation, methylation, cyclization.
