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 ...

Degradation of morpholine, piperidine, and pyrrolidine by mycobacteria: evidences for the involvement of a cytochrome P450

open access: yes, 1999
Nine bacterial strains that grew on morpholine and pyrrolidine as sole carbon, nitrogen, and energy sources were isolated from three different environments with no known morpholine contamination. One of these strains could also degrade piperidine.

3-(1<em>H</em>-Indol-3-yl)-4-(morpholin-4-yl)cyclobut-3-ene-1,2-dione

open access: yesMolbank, 2012
3-(1<em>H</em>-Indol-3-yl)-4-(morpholin-4-yl)cyclobut-3-ene-1,2-dione was obtained in good yields (72–82%) by nucleophilic substitution of 3-chloro-4-(1<em>H</em>-indol-3-yl)cyclobut-3-ene-1,2-dione with morpholine.

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.

A Role for Janus Cyclohexyl Ring Motifs in Medicinal Chemistry. Incorporation Into G‐Quadruplex Ligands and Anti‐Trypanosoma brucei Activity

open access: yesChemBioChem, Volume 27, Issue 21, 12 November 2026.
Naphthalene diimide (NDI) cores with peripheral fluorocyclohexyl ring systems are explored binding to G‐quadruplex DNA and were also assayed against the Trypanosoma brucei parasite. The most active compound of the series displayed nanomolar activity and suggested electrostatic interactions between the polarized cyclohexane and G‐Quad DNA.

Activating Triplet Excitons in COFs via Layer‐Bridging Co Single Atoms for Photocatalytic H2O2 Production and Tandem C─N Coupling

open access: yesAngewandte Chemie, Volume 138, Issue 42, 12 October 2026.
This work demonstrates a layer‐bridging coordination strategy of Co single atoms in COFs that promotes the formation and utilization of triplet excited states. The introduction of Co single atoms induces pronounced energy‐level splitting and enhanced spin–orbit coupling, facilitating the generation of 1O2 and O2•– for efficient photocatalytic H2O2 ...

o-Carboranylalkoxy-1,3,5-Triazine Derivatives: Synthesis, Characterization, X-ray Structural Studies, and Biological Activity

open access: yesMolecules, 2018
Morpholine- and bis(2-methoxyethyl)amine-substituted 1,3,5-triazine derivatives containing an alkoxy-o-carborane in the 6-position of the triazine ring were successfully synthesized.

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.
