(JOHN WILEY & SONS LTD, 1998-06)
The H-1 and C-13 NMR spectra of 2-phenyl-3H-naphtho[2,1-b][1,4]oxazin-3-one, 2-p-methoxyphenylnaphtho[1,2-d]oxazole and 2-phenylnaphtho[1,2-d]oxazole were totally assigned using a combination of one-and two-dimensional NMR ...
Succinyl-β-cyclodextrin: Influence of the substitution degree on albendazole inclusion complexes probed by NMR
(Elsevier Science, 2018-11)
Succinyl-β-CD derivatives were obtained by green synthesis with degrees of substitution (DS) 1.3 and 2.9. The spray-drying technique was used to obtain albendazole (ABZ):succinyl-β-CD inclusion complexes. Phase solubility ...
