—— | 6-methyl-4-naphthalen-1-yl-2-tetradecylsulfanyl-1, 4-dihydro-pyrimidine-5-carboxylic acid ethyl ester | 1104612-42-1 | C32H46N2O2S | 522.795 |
A wide range of readily available DHPMs and alcohols makes the presented reaction an attractive method to access biologically valuable 2-alkoxypyrimidine derivatives with rapid diversification.
A library of dihydropyrimidinones was synthesized via a “one-pot” three component Biginelli reaction using different aldehydes in combination with β-dicarbonyl compounds and urea. Selected 2-thiooxo and 2-imino analogs were also obtained with the Biginelli reaction from thiourea and guanidine hydrochloride, respectively. The products were screened in vitro for their β-secretase inhibitory activity. The majority of the compounds resulted to be active, with IC50 in the range 100 nM–50 μM.
