Beilstein Journal of Organic Chemistry, 2017 Diastereoselective radical coupling was achieved with chiral auxiliaries. The radicals were generated by anodic decarboxylation of five malonic acid derivatives. These were prepared from benzyl malonates and four menthol auxiliaries.

Angewandte Chemie International Edition, EarlyView.A stereoselective functionalization method of cyclic imines under mild organocatalytic conditions was developed. Bifunctional cinchona alkaloid catalysts combined with carefully optimized reaction conditions to suppress background reactivity enabled highly enantio‐ and diastereoselective addition reactions of malonates to cyclic imines.

]pyrimidin‐4‐ones from Highly Reactive Malonates
, 2010 A very simple and efficient procedure for the synthesis of novel 2-hydroxy-4H-pyrimido[1,2-a]pyrimidin-4-ones is described. Title compounds were obtained from the room temperature reaction of 2-aminopyrimidine and its substituted derivatives with bis(2,4,

Advanced Science, EarlyView.Variations in polymer conformations of unsaturated poly(n‐alkyl esters) driven by monomer‐level stereochemistry directly govern Li+ solvation structures in polymer host matrices. The synergistic strategies of polymer conformation control, UV‐induced interchain crosslinking, and end‐group fluorination are implemented for engineering advanced solid ...

Enantioselectively Organocatalytic Michael Addition of Ketones to Alkylidene Malonates
, 2016 An organocatalytic asymmetric Michael addition of ketones to alkylidene malonates has been developed. In the presence of 20 mol % of urea 1a or N-(pyrrolidin-2-ylmethyl)trifluoromethanesulfonamide 1j, the reactions of ketones with alkylidene malonates ...

Advanced Science, EarlyView.This work identifies acetylation‐dependent SDHA homeostasis as a determinant of tumor‐specific metabolic vulnerability. Guided by this mechanism, a modification‐selective inhibitor, ZPI‐3, selectively targets non‐acetylated SDHA, achieving tumor‐restricted SDH inhibition and effective bladder cancer control. Differential responses in clinical specimens
