Stereocontrolled Asymmetric Synthesis of α-Hydroxy-β-amino Acids. A Stereodivergent Approach
, 2016 The stereocontrolled asymmetric synthesis of α-hydroxy-β-amino acids has been investigated via the Lewis acid-promoted cyanation of (5R,6S)-2-acetoxy-4-(benzyloxycarbonyl)-5,6-diphenyl-2,3,5,6-tetrahydro-4H-1,4-oxazines with trimethylsilyl cyanide.

Stereoselective synthesis of alpha-hydroxy-beta-amino acids: the chiral pool approach [PDF]
, 2004 A method for the stereoselective homologation of alpha-amino acids into syn-alpha-hydroxy-beta-amino acids is described. based on the conversion of stereoisomeric cyanohydrins into trans-oxazolines. The synthetic potential of the method is illustrated in

An ETH‐LAD trip with unfavourable consequences: A case report
British Journal of Clinical Pharmacology, EarlyView.Numerous analogues of the psychedelic and internationally controlled hallucinogen LSD have been described; however, only a limited number have been systematically investigated. This report presents the first case with an analytically confirmed ingestion of ETH‐LAD (6‐ethyl‐6‐nor‐lysergic acid diethylamide), the N‐ethyl derivative of LSD.

Chemistry – A European Journal, EarlyView.Covalent linkage of a highly crystalline PHBV with a ductile P3HB4HB is shown to produce block copolymers with markedly enhanced extensibility and toughness, outperforming equivalent blends. The results demonstrate that polymer architecture, not composition alone, governs mechanical response, offering a route to biodegradable materials that combine ...

A proteomic investigation of forebrain regeneration in the leopard gecko (Eublepharis macularius)
Developmental Dynamics, EarlyView.Our investigation reveals ontogenetic, injury‐ and regeneration‐associated proteomic changes in the leopard gecko forebrain. Abstract Background The ability to replace lost or damaged neurons following an injury is termed reactive neurogenesis. Although reactive neurogenesis has been reported in several lizard species, the molecular mechanisms ...

Visible‐Light‐Mediated Synthesis of Biscoumarins Utilizing Photocaged Sulfonic Acid as the Catalyst
European Journal of Organic Chemistry, EarlyView.A mild visible light approach for the synthesis of biscoumarins utilizing arylazo sulfones as the photoacid generator under 467 nm irradiation is introduced. Throughout the years, biscoumarin derivatives, known for their diverse biological properties, have attracted extensive synthetic interest.
