Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Morpholines — (II)

open access: yesZeitschrift für Naturforschung B, 1970
The new route to the synthesis of 3-oxo-1,4-oxazines 1 has been extended. N-aryl-N-chloroacetyl-m-nitro-phenacyl amines afford either only oxazine, or beta-lactam or both depending on the nature of the N-aryl substituent. A set of rules indicates from which precursors beta-lactam, as against morpholine formation, may be expected.

Molecular Glue Degraders in Early Development for Cancer Therapy

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Molecular glue degraders are an emerging class of small molecule allosteric modulators that induce or stabilize protein‐protein interactions, enabling targeted degradation of previously intractable proteins. By redirecting E3 ligases to recognize neosubstrates, proteins that are not typically recognized by a specific E3 ubiquitin ligase, they ...

Synthesis and glycosidase inhibitory profiles of functionalised morpholines and oxazepanes

open access: yes, 2011
In this work libraries of morpholines and oxazepanes have been prepared via the reductive amination reaction between dialdehydes, derived from carbohydrates, and a range of amines. In this way, functionalised morpholines and oxazepanes have been prepared

Beyond HEMA: Shifts in the (Meth)acrylate Composition of Matched Nail Cosmetics Between 2023 and 2026

open access: yesContact Dermatitis, EarlyView.
In 127 matched nail cosmetics, 2‐hydroxyethyl methacrylate (HEMA) and Di‐HEMA trimethylhexyl dicarbamate (Di‐HEMA TMHDC) listings decreased by approximately 75% between 2023 and 2026. Several other (meth)acrylate‐related ingredients also showed substantial increases or decreases.

Unveiling contrasting iron efficiency strategies in common bean (Phaseolus vulgaris L.) genotypes under iron deficiency

open access: yesPlant Biology, EarlyView.
Common bean genotypes differ in their iron acquisition through distinct Strategy I responses and root exudation patterns. Abstract Iron (Fe) deficiency in food crops, particularly on calcareous soils, limits productivity and human nutrition. This study investigated two common bean (Phaseolus vulgaris) genotypes, Guaymí (high Fe‐accumulating, HI) and ...

Morpholines-(I)

open access: yesZeitschrift für Naturforschung B, 1970
ω- (N-aryl-chloracetamido) -acetophenones have been cyclized with triethylamine in warm benzene solution to the corresponding 1,4-oxazines. The reaction appears to be general for any N-aryl substituent, as long as an overall electron-withdrawing substituent is present para- or meta, in the aromatic nucleus of the acetophenone moiety.

Thiolane Sulfoximines as Azide Surrogates for Quinolyl Nitrenes: Photochemical Access to Ortho‐Diaminoquinolines

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Thiolane sulfoximines provide practical and safer surrogates for hazardous azides in nitrene photochemistry, enabling direct access to 7,8‐diaminoquinolines and fused δ‐lactams. DFT calculations support the reaction mechanism and rationalize product selectivity.
