A two-level library of 3 beta-amido-3 alpha-hydroxy-5 alpha-androstane-17-one compounds was synthesized from a steroid precursor using the solution-phase parallel synthesis. The compounds were easily obtained in high purity by regioselective aminolysis of the oxirane intermediate followed by acylation of the amine. Since oxiranes can be generated from readily available ketones or alkenes, the proposed strategy give access to a large series of compounds. (C) 1998 Elsevier Science Ltd. All rights reserved.
