Dialkylaluminium 2-imidazolylphenolates: Synthesis, characterization and ring-opening polymerization behavior towards lactides [PDF]

, 2013
The stoichiometric reaction of the 2-imidazolylphenols (L1–L9) with the trialkylaluminium reagents AlR₃ (R = Me, Et and iBu), afforded the corresponding dialkylaluminium 2-imidazolylphenolate complexes [R₂Al(L1–L9)] (C1–C11), which were characterized by ...

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Enantioselective cyanation via radical-mediated C–C single bond cleavage for synthesis of chiral dinitriles

Nature Communications, 2019
Ring-opening reaction via selective cleavage of C–C bond is a powerful strategy to increase molecular complexity. Here the authors present the facile synthesis of chiral 1,5- and 1,6-dinitriles via the radical-mediated ring-opening and enantioselective ...

PHOTOCHEMICAL RING-OPENING IN meso-CHLORINATED CHLOROPHYLLS [PDF]

, 1990
Irradiation of 20-chloro-chlorophylls of the a-type with visible light produces long-wavelength shifted photoproducts, which transform in the dark to linear tetrapyrroles (bile pigments).

The Role of Invasive Procedures in the Treatment of Complicated Gastrointestinal Graft‐Versus‐Host Disease in Pediatric Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Gastrointestinal graft‐versus‐host disease (GI GVHD) following hematopoietic stem cell transplant is typically managed with medical therapy, but surgery and angioembolization may be warranted in selected cases with life‐threatening complications.

Cationic-anionic synchronous ring-opening polymerization

Nature Communications
Chemical reactions with incompatible mechanisms (such as nucleophilic reactions and electrophilic reactions, cationic polymerization and anionic polymerization) are usually difficult to perform simultaneously in one-pot.

2-Methylsulfanylbenzo[f]isoquinoline [PDF]

, 2015
S-Methylation of a 4-(naphth-2-yl)-β-thiolactam gives an intermediate 4-(naphth-2-yl) substituted 1-azetine which undergoes a [2+2] ring-opening followed by electrocyclic ring closure of the resulting 2-azadiene to give a benzo[f ...
