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 ...

Attempted Synthesis of Vinca Alkaloids Condensed with Three-Membered Rings
Molecules, 2018 Our successful work for the synthesis of cyclopropanated vinblastine and its derivatives by the Simmons–Smith reaction was followed to build up further three-membered rings into the 14,15-position of the vindoline part of the dimer alkaloid ...

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.

Modulating Fatty Acid Epoxidation vs Hydroxylation in a Fungal Peroxygenase
ACS Catalysis, 2019 Unspecific peroxygenases (UPOs) are fungal secreted counterparts of the cytochrome P450 monooxygenases present in most living cells. Both enzyme types share the ability to perform selective oxygenation reactions.

Carbon Energy, EarlyView.A combination of visible light and thermal energy accelerates the CO formation rate up to 57 times compared to dark conditions using a 3Cu/CeTiO2−x catalyst. Kinetic analysis, as well as steady state and transient spectroscopy, was applied under photocatalytic conditions to analyze and disentangle the reaction channels under dark and illuminated ...
