Abstact

N-Methylpyrrolidone is one of several chemotypes that have been described as a mimetic of acetyl-lysine in the development of bromodomain inhibitors. In this paper, we describe the synthesis of a 4-phenyl substituted analogue - 1-methyl-4-phenylpyrrolidin-2-one - and the use of aryl substitution reactions as a divergent route for derivatives. Ultimately, this has led to structurally complex, chiral compounds with progressively improved affinity as inhibitors of bromodomain-containing protein 4.
