Take your new partner by the hand: Chiral secondary and tertiary alkyl trifluoroborate salts undergo rhodium‐catalyzed 1,2‐addition to aldehydes with complete stereoretention (handedness) in all cases, enabling the creation of quaternary stereogenic centers with essentially perfect enantioselectivity (see scheme; cod=cycloocta‐1,5‐diene).
牵手您的新搭档:在所有情况下,手性仲和叔烷基三氟硼酸盐都经过铑催化的1,2-醛加成到醛中,并具有完全的立体保留(手性),从而可以创建具有基本完美对映选择性的四元立体中心(见方案) ; cod = cycloocta-1,5-diene)。
