The stereochemical features of per-O-acetyl-cyclomaltoheptaose (-beta-cyclodextrin) have been investigated in solution by NMR spectroscopy, and the deviation of functionalised glucopyranose rings from 4C(1) chairs to skew-type conformations has been detected.

Abstract Mixed methylated/carbamoylated cyclodextrins constitute a new class of chiral complexing agents for NMR spectroscopy, which are able to induce anisochrony of enantiomeric mixtures of apolar trisubstituted allenes and polar derivatized compounds most of which are endowed with a π‐acidic 3,5‐dinitrophenyl ring. The differing contribution to enantiorecognition phenomena of the nature and location of the functional groups on the two cyclodextrin rims was shown. Some interesting aspects of the ...

The conformation in solution of exhaustively derivatized mixed cyclomaltooligosaccharides (cyclodextrins) has been defined by NMR spectroscopy. Both tilting of glucopyranose units about the glycosidic linkages and ring deviations from the 4C1 chair conformation are detected, the entities of which are strongly dependent on the nature of the derivatizing groups.

Objective: The Transatlantic Australasian Retroperitoneal Sarcoma Working Group conducted a retrospective study on the disease course and clinical management of ganglioneuromas. Background: Ganglioneuromas are rare tumors derived from neural crest cells. Data on these tumors remain limited to case reports and single-institution case series. Methods: Patients of all ages with pathologically confirmed primary retroperitoneal, intra-abdominal, and pelvic ganglioneuromas between January 1, 2000, and ...
