Catalysis of a Bis-Caffeine Palladium(II) NHC-Pincer Complex

open access: yesInorganics, 2023
A tridentate bis-NHC Pd complex, based on caffeine, was studied for its catalytic activity. This complex displayed a high catalytic activity in the Suzuki–Miyaura and Mizoroki–Heck cross-coupling reactions of aryl halides.

Divergent strategy for the synthesis of α-aryl-substituted fosmidomycin analogues [PDF]

open access: yes, 2007
Fosmidomycin is the first representative of a new class of antimalarial drugs acting through inhibition of 1-deoxy-D-xylulose 5-phosphate ( DOXP) reductoisomerase (DXR), an essential enzyme in the non-mevalonate pathway for the synthesis of isoprenoids ...

Assembly of (hetero)aryl sulfilimines via copper-catalyzed enantioselective S-arylation of sulfenamides with (hetero)aryl Iodides

open access: yesNature Communications
The (hetero)aryl sulfoximines are important structures for developing bioactive molecules, whose synthesis relies on oxidation of (hetero)aryl sulfilimines. However, asymmetric approaches for assembling (hetero)aryl sulfilimines are still rare.
