In this study, we report the synthesis of three new derivatives of betulinic acid, a pentacyclic triterpenoid known for its antitumor activity. These derivatives were synthesized via amide bond formation at the C-28 position using 3-[(Ethylimino)meth...
Crystal molecular structure of 3-(anthracen-2′-yl)-ortho-carborane was determined by single crystal X-ray diffraction study at 100 K. The asymmetric cell unit contains two enantiomeric pairs of molecules, in one of which the intramolecular dihy...
Organic azides are traditionally used in organic synthesis to obtain a wide variety of chemical compounds. This prompted us to report the synthesis of a new polyfluorinated aryl azide, 2,2,3,3-tetrafluoropropyl 4-azido-2,3,5,6-tetrafluorobenzoate, wh...
N,N-Ditosyl-2-aminodiphenylamine was prepared by the tosylation of 2-aminodiphenylamine with tosylchloride in dichloromethane. Unwanted isomers owing to the tosylation of the diarylamine were not formed. This compound was fully characterized by IR, U...
We report the synthesis and characterization of the novel pyridinium salts from (E)-2-(pyridin-4-ylmethylene)hydrazine-1-carboximidamide. The pyridinium salts were obtained via the reaction of guanylhydrazone derived from pyridine-4-carbaldehyde with...
3-(4-hydroxy-2,3,5-trimethylphenyl)-3-(4-hydroxyphenyl)isobenzofuran-1(3H)-one is a derivative of the well-known acid/base indicator, phenolphthalein. We report the synthesis and the molecular structure of the title compound as determined by single-c...
The compound dichloro[bis(diisopropylphosphorimidoyl-κN-(4,6-dimethylpyrimidine-κN))pyrrole-κN]yttrium(III) was synthesized from one equivalent of NaL [L = 2,5-[iPr2P=N(PymMe)]2NH(C4H2); PymMe = 4,6-dimethylpyrimidine] and YCl3(THF)...
We describe the synthesis of (±)-2-(4-isobutylphenyl)-N-(naphthalen-1-yl)propanamide, followed by comprehensive structural characterization. The compound was analyzed through melting point determination, 1H and 13C NMR spectroscopy, infrared s...
