Synthesis and Molecular Docking Studies of Novel 2-(2-Amino-6-Phenyl-4-Pyrimidinylamino) Ethanol Derivatives: Using Ring-Opening Reactions of Cyclic Ketene-N,O-Acetal

A series of six novel 2-(2-amino-6-phenyl-4-pyrimidinylamino) ethanol derivatives have been synthesized starting from commercially available substituted acetophenones via OxoketeneDithioacetals with high yields. Ketene dithioacetals to react with 2-aminoethanol or l-amino-2-propanol to afford the corresponding substituted 2-methyleneoxazolidines which are utilized in the synthesis of 6-aryl-2-amino-4-pyrimidinamine Derivatives. The molecular docking studies revealed that all the synthesized compounds best fit into the active site of HDAC2, anti-cancer protein.
