The synthesis of a series of N-alkylated 4-(4′ aminobenzyl)-2-oxazolidinones is described using a synthetically useful scheme which avoids the use of phosgene—since the derivatization is undertaken with the oxazolidin-2-one ring intact. The compounds were tested for human placental aromatase (AR) inhibition in vitro, using [1β, 2β-3H] androstenedione as substrate for the AR enzyme. The compounds were found, in general, ...
