Design Rules for Controlling Connectivity, Topology, and Sorting Using Hydrogen‐Bonded Pairs and Aromatic Components in Palladium(II)‐Based Interlocked and Foldameric Systems

Angewandte Chemie, EarlyView.
We have established a set of design rules which combine Pd(II) metal coordination, complementary geometries, complementary interligand hydrogen bonding and π─π interactions for predictable self‐assembly of Pd(II)‐based species such as metallo‐foldamers, cyclic species a metallo‐interlocked clippane. The species persist in a combinatorial mixture due to

Alkyltransferase Ribozyme for Site‐Specific N4‐Cytidine Alkylation

Angewandte Chemie, EarlyView.
CSAR is the first ribozyme that catalyzes direct alkylation of an exocyclic amino group of an RNA nucleobase. The ribozyme was isolated as a self‐labeling catalyst from an in vitro selection library and engineered into a trans‐active ribozyme that catalyzes the transfer of a benzyl group from an O6‐modifed guanine to the N4 amino group of a specific ...

Strategies Toward Accessing Enantioenriched (Hetero)Benzo‐Fused 5‐ and 6‐ Membered Rings via Intermolecular Carbometalation

Angewandte Chemie, EarlyView.
The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

Alcohol‐Directed Carboamination of Conjugated Enynes

Angewandte Chemie, EarlyView.
The first general three‐component intermolecular Pd‐catalyzed carboamination of conjugated enynes enables the coupling of anilines and aryl triflates to produce functionalized allenic amines, utilizing a native alcohol directing group to control regioselectivity.
