Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Hydrogels Formed by the Self‐Assembly of Collagen‐Mimetic Peptides With a Constrained Backbone Structure

open access: yesChemistry – A European Journal, EarlyView.
Kinked collagen‐mimetic peptides (kinkCMPs), whose backbone is constrained by a disulfide bond, are designed to induce hydrogel formation. The kinked backbone promotes supramolecular assembly into tunable hydrogels with thermal stability depending on length.
