Starting from a variety of substituted chroman-4-ones, a highly enantioselective CBS reduction using in situ-generated B-H catalyst gave (S)-chroman-4-ols. Azide inversion and reduction gave crude (R)-chroman-4-amines, which could be purified without chromatography by isolation as the (R)-mandelic or D-tartaric acid salts with good yields and excellent ee.
