Switching Diastereoselectivity in Catalytic Enantioselective (3+2) Cycloadditions of Azomethine Ylides Promoted by Metal Salts and Privileged Segphos-Derived Ligands was written by Caleffi, Guilherme S.;Larranaga, Olatz;Ferrandiz-Saperas, Marcos;Costa, Paulo R. R.;Najera, Carmen;de Cozar, Abel;Cossio, Fernando P.;Sansano, Jose M.. And the article was included in Journal of Organic Chemistry in 2019.Name: 3-Acryloyloxazolidin-2-one This article mentions the following:
Catalytic enantioselective 1,3-dipolar cycloaddition between imino esters and electrophilic alkenes, employing chiral metal complexes derived from copper(I) and silver(I) salts and (S)-DM- or (S)-DTBM-Segphos as ligands produces diastereodivergently exo- or endo-cycloadducts, resp. The effect of the functional group of the dipolarophile and the fine tuning of the catalyst plays an important role in promoting reverse diastereoselectivities. The origins of exptl. observed enantioselectivity and diastereoselectivity data, as well as the origin of the observed switched endo/exo ratios, are also explained by means of d. functional theory calculations In the experiment, the researchers used many compounds, for example, 3-Acryloyloxazolidin-2-one (cas: 2043-21-2Name: 3-Acryloyloxazolidin-2-one).
3-Acryloyloxazolidin-2-one (cas: 2043-21-2) belongs to oxazolidine derivatives. Oxazolidine-based compounds have started to attract attention also in the medicinal and materials chemistry fields. Oxazolidines are commonly used as metal ligands in asymmetric catalysis, synthetic intermediates in organic synthesis, and also used as the protecting groups.Name: 3-Acryloyloxazolidin-2-one
