Abstract

The syntheses of all possible stereoisomers of desfluorinated side products of the potent antihypertensive β-blocker nebivolol are reported. A straightforward approach using a common racemic precursor was employed to obtain the desired optically active building blocks. For one series of compounds, a Sharpless asymmetric epoxidation (SAE) route yielded in a direct fashion the required compounds whereas a Mitsunobu reaction was selected to obtain the Other series of compounds. This offers a flexible approach to all desfluoronebivolol side-products in order to fully characterize them.
