Terpestacin Core Structure. Control of Stereochemistry

, 2016
The α-hydroxycyclopentenone core structure of terpestacin has been prepared in a model system through an allene ether Nazarov cyclization of an alkylidene-γ-butyrolactone followed by regio- and stereoselective alkylation reactions. The stereochemistry at

Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, EarlyView.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.
