Isothiazologuanosine (tzG) as Environmentally Sensitive Fluorescent Reporter in RNA
Angewandte Chemie, EarlyView.The emissive isothiazologuanosine analog tzG is synthesized for the first time as RNA phosphoramidite building block for solid‐phase synthesis. Due to its isomorphic and isofunctional characteristics, tzG forms Watson–Crick base pairs and can be used as fluorescent probe to monitor (deoxy)ribozyme activity.

Aza-PNA: Engineering E‑Rotamer Selectivity Directed by Intramolecular H‑bonding
, 2022 The replacement of α(CH2) by NH in monomers of standard aeg PNA and its homologue β-ala PNA leads to respective aza-PNA monomers (1 and 2) in which the NαH can form either an 8-membered H-bonded ring with folding of the backbone (DMSO and water) or a 5 ...

Chemical Switching Between B2N and B2C Homoaromaticity
Angewandte Chemie, EarlyView.We report the synthesis of homoaromatic 1‐aza‐2,4‐diazadiboretane with a bicyclic four‐membered NB2C motif and demonstrate experimentally and theoretically that the homoaromatic delocalization can also be chemically shifted from the B2N to the B2C moiety by deprotonation of the ring carbon atom.

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 ...
