Chiral Heterocyclic Ligands. XI. Self-assembly and X-Ray Crystal Structures of Chiral Silver Coordination Polymers of (S)-(-)-Nicotine [PDF]

open access: yes, 1999
Three chiral coordination polymers have been prepared by reaction of (S)-(-)-nicotine with silver(I) salts. X-Ray crystal structure determinations revealed that these all contain polymer chains in which the nicotine molecule acts as a bridging ligand ...

Ribosomal Synthesis of Topologically Defined Thioisoindole‐Bridged Bicyclic Peptides

open access: yesAngewandte Chemie, EarlyView.
A flexible in vitro translation (FIT) system‐based strategy for ribosomal synthesis of thioisoindole‐bridged bicyclic (TiB) peptides is developed. The flexizyme substrate Ac‐Ala(NtBA)Sc‐CME is efficiently incorporated into FIT to generate ribosomal peptides bearing N‐terminal Ac‐Ala(NtBA)Sc as the cyclization handle, which after mild deprotection ...
