Zhou, Kexu published the artcileCopper-catalyzed aerobic asymmetric cross-dehydrogenative coupling of C(sp³)-H bonds driven by visible light, Name: (3aS,3a’S,8aR,8a’R)-2,2′-(Cyclobutane-1,1-diyl)bis(3a,8a-dihydro-8H-indeno[1,2-d]oxazole), the publication is Green Chemistry (2020), 22(14), 4597-4603, database is CAplus.

A chiral-copper catalyst initiates the visible-light-driven oxidative CDC reaction by mol. oxygen, and governed the stereochem. In this way, a diastereo- and enantioselective synthesis of (imidazolyl)xanthenes such as I [R¹ = Me, Ph, Bn; R² = Me, cyclopropyl, Ph, etc.] via cross-dehydrogenative coupling between carbonyl compounds and xanthene derivatives was achieved. This work provided an economic and manageable approach to stereoselective C-C bond formation, and demonstrated a potential application of chiral copper catalysts in difficult asym. photochem. reactions.

Sibi, Mukund P. published the artcileEnantioselective intermolecular free radical conjugate additions. Application of a pyrazole template, SDS of cas: 182122-10-7, the publication is Tetrahedron Letters (1997), 38(34), 5955-5958, database is CAplus.

An achiral pyrazole template has been evaluated in enantioselective conjugate radical additions The enantioselectivity using the pyrazole template is inferior to those obtained from an oxazolidinone template. The two templates give products of opposite configuration using the same chiral Lewis acid.

Zhang, Zi-Qi published the artcileEnantioselective Copper-Catalyzed 1,5-Cyanotrifluoromethylation of Vinylcyclopropanes, Application In Synthesis of 182122-10-7, the publication is Organic Letters (2019), 21(20), 8256-8260, database is CAplus and MEDLINE.

A copper-catalyzed enantioselective 1,5-cyanotrifluoromethylation of vinylcyclopropanes has been developed using a radical relay strategy. This asym. reaction has demonstrated high enantioselective control, broad substrate scope, and mild conditions. Initiated by the in situ generated CF₃ radical from Togni’s reagent, this method offers a new solution for remote enantioselective bifunctionalization of alkenes and thus provides a straightforward way for the synthesis of chiral CF₃-containing internal alkenylnitriles.
