Uranium(IV) BINOLate Heterobimetallics: Synthesis and Reactivity in an Asymmetric Diels-Alder Reaction was written by Robinson, Jerome R.;Carroll, Patrick J.;Walsh, Patrick J.;Schelter, Eric J.. And the article was included in Organometallics in 2013.Category: oxazolidine This article mentions the following:
The first heterobimetallic BINOLate complexes incorporating uranium were prepared, and their reactivity in an asym. 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. Addnl., a simple workup procedure to obtain organic products free of the trace radioactivity present in the reaction mixtures is described. In the experiment, the researchers used many compounds, for example, 3-Acryloyloxazolidin-2-one (cas: 2043-21-2Category: oxazolidine).
3-Acryloyloxazolidin-2-one (cas: 2043-21-2) belongs to oxazolidine derivatives. Oxazolidine-based compounds are well-known chiral auxiliaries and strategic molecular moieties in chemistry since they can effectively mask or mimic amino acid units or amino alcohols. Oxazolidines are well known as key portions of bioactive molecules or precursors of chiral molecules, as well as established chiral auxiliaries.Category: oxazolidine
