  A general practical approach to hetero(aromatic) and aliphatic P(O)Me2-substituted derivatives is elaborated. The key synthetic step was a [Pd]-mediated C–P coupling of (hetero)aryl bromides/iodides with HP(O)Me2. The P(O)Me2 substituent was shown to dramatically increase solubility and decrease lipophilicity of organic compounds. This tactic was used to improve the solubility of the antihypertensive
