Nassar Y, Rodier F, Bigot A, Cruciani P, Ferey V, Daumas M, et al.
Org Lett . 2025 Mar; PMID: 40052663
A cross-coupling reaction between an enol triflate and an aryl Grignard reagent using a copper catalyst, followed by a deprotection step, a Mitsunobu reaction, and a saponification, allowed for the...

Nat Commun . 2023 Aug; 14(1):4638. PMID: 37532729
Ligands and additives are often utilized to stabilize low-valent catalytic metal species experimentally, while their role in suppressing metal deposition has been less studied. Herein, an on-cycle mechanism is reported...

Polak P, Cossy J
Chemistry . 2022 Mar; 28(27):e202104311. PMID: 35238093
The synthesis of 2-C-glycals and 2-C-ribals was achieved in good yields using a nickel-catalyzed cross-coupling between 2-iodoglycals and 2-iodoribal respectively and Grignard reagents. The prepared 2-C-glycals and ribals were then...
