Toward homochiral protocells in noncatalytic peptide systems

, 2009
The activation-polymerization-epimerization-depolymerization (APED) model of Plasson et al. has recently been proposed as a mechanism for the evolution of homochirality on prebiotic Earth.

Structural Revision of the C16 Sesquiterpene Hegelenether and the Mechanism of C6‐Methylation in Terpene Biosynthesis

Angewandte Chemie International Edition, EarlyView.
The structure of the non‐canonical C16 sesquiterpene named hegelenether was revised to the structure of marxdiol, and its absolute configuration was assigned. Isotopic labeling experiments revealed the stereochemical course of the methyltransferase involved in its biosynthesis.

Tertiary alcohol preferred: Hydroxylation of trans-3-methyl-L-proline with proline hydroxylases

Beilstein Journal of Organic Chemistry, 2011
The enzymatic synthesis of tertiary alcohols by the stereospecific oxidation of tertiary alkyl centers is a most-straightforward but challenging approach, since these positions are sterically hindered.

Valorization of fishing industry by‐products for biodiesel production: Unlocking the potential of residual fish oil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fishing waste and its by‐products, whether naturally occurring or generated by the processing industry, represent a significant opportunity for producing high‐value products. These often discarded or underutilized residues can be converted into various valuable products through advanced processing technologies. Among the potential products are

Studying the Outcomes and Mechanisms of Carbocationic Rearrangements Using Algorithm‐Augmented Experimentation

ChemistryEurope, EarlyView.
HopCat, a hybrid algorithm combining rule‐based transformations with quantum‐informed kinetics, can be applied to acid‐catalyzed terpenoid rearrangements. In synergy with human chemists and nuclear magnetic resonance analysis, it facilitates product assignment, candidate selection, and reconstruction of complex mechanistic pathways.

Synthesis of α‐Pentafluorosulfanylated‐β2,3‐Amino Esters

ChemistryEurope, EarlyView.
De novo α‐SF5‐β2,3‐amino esters are now accessible through a straightforward aza‐Michael reaction using a series of newly developed (E)‐α‐SF5‐α,β‐unsaturated esters. Two new, highly functionalized, contiguous tertiary stereocenters are formed with diastereodivergence governed by the choice of solvent and/or base.
