Compound libraries are important requirement in target-based drug discovery. In the present work, a small focused compound library based on β-aminoketone scaffold has been prepared combining microwave-assisted organic synthesis (MAOS) with polymer-assisted solutionphasesynthesis (PASPS) and replacing reaction workup standard purification procedures with solidphase extraction (SPE). Specifically
and lithium aluminum hydride (LAH) provided the corresponding 1,3-aminoalcohols in high ee's (80–88%). This process was developed and applied to the synthesis of LY248686 (1), a potent inhibitor of serotonin (5HT) and norepinephrine (NE) uptake. Absolute configurations have been established by single crystal x-ray analysis.
