Nonnative Thiol and Aniline Methylation, Including Enantioselective Dithiol Desymmetrization, by Multicomponent Cobamide‐Dependent Methyltransferases Using Unactivated Methyl Donors

Angewandte Chemie, EarlyView.
Mixed MtaABC/MtgABC methyltransferase systems were developed for non‐native thiol and aniline methylation using the unactivated methyl donors methanol and glycine betaine. The platform enabled site‐selective and enantioselective methylation with turnover number up to 6000, representing the first enantioselective non‐native catalysis by cobamide ...

Palladium-catalyzed asymmetric carbene coupling en route to inherently chiral heptagon-containing polyarenes

Nature Communications
Developing facile and direct synthesis routes for enantioselective construction of cyclic π-conjugated molecules is crucial. However, originate chirality from the distorted structure around heptagon-containing polyarenes is largely overlooked, the ...

Enantioselective synthesis of cyclic sulfamidates via Pd-catalyzed hydrogenation

, 2008
Using Pd(CF(3)CO(2))(2)/(SS)-f-binaphane as the catalyst, an efficient enantioselective synthesis of cyclic sulfamidates was developed via asymmetric hydrogenation of the corresponding cyclic imines in 2,2,2-trifluoroethanol at room temperature with high

Cobalt‐Catalyzed Asymmetric Construction of Boron Stereocenters With C–N Axial Chirality

Advanced Science, EarlyView.
A cobalt/Salox‐catalyzed one‐pot annulation enables enantioselective formation of B‐stereogenic centers and C─N axial chirality via C─H/N─H annulation, affording diverse fluorescent products with high stereocontrol and optoelectronic potential. ABSTRACT The efficient construction of boron stereogenic centers alongside axial chirality remains a ...

Enantioselective desymmetrization strategy of prochiral 1,3-diols in natural product synthesis

Beilstein Journal of Organic Chemistry
Enantioselective desymmetrization is employed as a powerful tool for the creation of chiral centers. Within this scope, the enantioselective desymmetrization of prochiral 1,3-diols, which generates chiral centers by enantioselective functionalization of ...

Enanatioselective Switch and Potential Applications in Biocatalysis

CHIMIA, 2023
Enantioselectivity has always been a key feature of enzymatic synthesis. In some cases, when enzymes are not strictly enantioselective, by tuning the reaction conditions it is possible to induce an enantioselective switch.

Enantioselective Synthesis of (−)‐Halenaquinone

Angewandte Chemie International Edition, 2018
AbstractThe efficient, 12–14 step (LLS) total synthesis of (−)‐halenaquinone has been achieved. Key steps in the synthetic sequence include: (a) proline sulfonamide‐catalyzed, Yamada–Otani reaction to establish the C6 all‐carbon quaternary stereocenter, (b) multiple, novel palladium‐mediated oxidative cyclizations to introduce the furan moiety, and (c)
