The chemoselective alkynylation of N-sulfonylamides versus amides and carbamates using TMS-EBX as an alkynylating agent leads to the formation of non-symmetrical tetrahydropyrazines from orthogonally protected diamines. The Royal Society of Chemistry 2013

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.

Barrett, Anthony G. M.,Lana, J. Carlos A.,Tograie, Shahrzad
, p. 300 - 301 (2007/10/02)
The regioselectivity of diamine monoacylation has been controlled by selective complexation with 18-crown-6 and a proton source.
