Total Synthesis and Complete Stereochemical Assignment of Amphirionin‐5, a Potent Natural Osteoblasts Proliferator

ChemistryEurope, EarlyView.
The convergent total synthesis of a candidate diastereomer of amphirionin‐5 was accomplished in 22 steps via the coupling of the C1‐C16 enone segment and the C17‐C28 aldehyde segment using Stetter reaction. The overall stereochemistry of amphirionin‐5 was fully assigned, based on the comparison of spectroscopic and chiroptical data between the ...

Introducing the Cis‐2,3‐Bis(trifluoromethyl)cyclopropyl Chemotype: Late‐Stage Installation and Stereoelectronic Properties

ChemistryEurope, EarlyView.
The cis‐2,3‐bis(trifluoromethyl)cyclopropyl chemotype is introduced. The steric demand of this motif is intermediate between that of the heptafluoroisopropyl and prefluorotertbutyl groups; yet, it induces significantly less lipophilicity than these due to its facial polarity.

Bioorthogonal Chemistry in Biomolecule Quantification: A Review of Reactions and Strategies

Chemistry – A European Journal, EarlyView.
This review summarizes the application of catalyst‐free bioorthogonal reactions: Staudinger ligation, strain promoted azide alkyne cycloaddition, inverse electron‐demand Diels–Alder, and 2‐cyanobenzothiazole cysteine condensation in the semi‐quantitative and quantitative analysis of biomolecules.
