Asymmetric hydroboration of 1,3-cyclohexadiene with 4R produces the allylborane 5RR as essentially a single diastereomer (i.e., no observable 5RS), and its addition to representative aldehydes provides 9RS (52-75%) with excellent selectivity (94-99%

The asymmetric gamma-methoxyallylboration of aldehydes with the configurationally very stable 1 gives nonracemic threo-beta-methoxyhomoallylic alcohols 7 (65-93%) with excellent selectivity (96-99% de, 98-99% ee). The corresponding homoallylic amines

The first asymmetric γ-alkoxyallylboration of representative ketones provides β-alkoxy tert-homoallylic alcohols 10 whose diastereoselectivities range from 99% syn (acetophenone) to 99% anti (pinacolone) both with high ee (>95%). This distribution
