Remarkable levels of enantioswitching in catalytic asymmetric hydroboration

Article abstract of DOI:10.1021/ol101932q

TADDOL-derived phosphites and phosphoramidites are effective ligands for rhodium-catalyzed asymmetric hydroborations of β,γ-unsaturated amides, achieving up to 99% ee. However, the sense of stereoinduction, R or S, is surprisingly dependent on rather subt
