资源简介：
The first heterobimetallic BINOLate complexes incorporating
uranium
were prepared, and their reactivity in an asymmetric Diels–Alder
reaction was investigated. The contributions of both the Li+ and UIV cations to the reaction selectivity were addressed
through control of the two different Lewis acidic centers. The presence
of an anionic ligand in the seventh coordination site of the central
uranium cation resulted in enhanced selectivity compared to the RE(III)
catalyst with the same alkali metal cation and represents the highest
enantioselectivities obtained with a uranium-based catalyst to date.
Additionally, we describe a simple workup procedure to obtain organic
products free of the trace radioactivity present in the reaction mixtures.
