ChemSusChem, Volume 18, Issue 6, March 15, 2025.Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Structure and stereochemistry of some neothiobinupharidine methiodides
, 1986 Quaternization of neothiobinupharidine was examinated. The structure and stereochemistry of three methiodides were proposed on the basis of 13C NMR and 1H NMR spectroscopy and Hofmann degradation.

General Anesthetics: Aspects of Chirality, Pharmacodynamics, and Pharmacokinetics
PharmaceuticalsThe introduction of general anesthetics in the mid-19th century is considered one of the greatest contributions to medical practice. It was the first time that complicated surgical interventions became feasible, without putting an excessive strain on the

The Absolute Stereochemistry of Variabilin and Related Sesterterpene Tetronic Acids
, 1994 The absolute stereochemistry of the marine metabolite variabilin (1). has been suggested by degradation. The absolute stereochemistry of related marine metabolites, ircinin-1 (2), ircinin-2 (3), (8£,13Z,20Z)-strobobilin (4) and (8Z,13£,20Z)-strobobilin ...

Drug Testing and Analysis, EarlyView.Δ8‐THC and Δ9‐THC showed comparable metabolic profiles. In contrast, Δ10‐THC underwent extensive glucuronidation and hydroxylation, with only minor formation of a carboxy metabolite, indicating a markedly different metabolic pathway. These differences may increase the risk of misidentification and misinterpretation in cannabis drug testing.

European Journal of Organic Chemistry, EarlyView.A Pd(0)‐catalyzed cyclotrimerization of benzoCOTynes to form tri(benzo[8]annulenes) was developed. Three distinct isomers were isolated and structurally characterized by single‐crystal X‐ray diffraction. Ligand modulation proved crucial for enhancing regioselectivity: P(4‐OMePh), and (S)‐tBu‐Phox promoted the formation of the symmetric isomers.

European Journal of Organic Chemistry, EarlyView.Chiral tri‐ and pentahydroxy spirocyclopentane‐indolizidines were synthesized using lithium diisopropylamide “LDA” promoted diallylation and tetrahydrofuran “THF” ring‐opening in a one‐pot procedure as a key step. The sequence leading to the targeted hydroxy‐spiroindolizidines was achieved by cis‐dihydroxylation followed by reduction of the enamine and
