, p. 251 - 254 (2007/10/02)
Various 2-substituted 1,4-dihydro-4,4,6-trimethyl-1-phenylpyrimidines and 1,6-dihydro-4,6,6-trimethylpyrimidines were synthesized independently.For these dihydropyrimidines, the physical data such as the uv, ir, and nmr spectra and the oxidation potential were compared. 2-Dimethylamino substituted dihydropyrimidine showed the lowest oxidation potential, which expected the similar reducing ability as dihydropyridines.
CYCLIZATION OF GUANIDINES WITH α,β-UNSATURATED KETONES: IMPROVED SYNTHESIS OF 2-AMINODIHYDROPYRIMIDINE DERIVATIVES CONTAINING GUANIDINE MOIETY
Kim, Yong Hae,Yoon, Cheol Min,Lee, Nam Jin
, p. 49 - 52 (2007/10/02)
3,4-Dihydro-2-amino pyrimidine derivatives 4a, 4b, 4c, 4d, 4e and 4f containing guanidine moiety were succesfully synthesized by cyclization of free N-monosubstituted guanidines with α,β-unsaturated ketones in tertiary butanol at 25 deg C.These products a
