3-<i>O</i>-But-2-ynoyl-28-<i>O</i>′-acetylbetulin
Abstract
The aim of the work was the synthesis of a new 28-acetylbetulin derivative containing an ester group with a carbon–carbon triple bond in the C3 position. To obtain the title compound, a reaction of 28-acetylbetulin with but-2-ynoic acid was carried out according to the Steglich method. The synthetized compound was fully characterized by analyzing the nuclear magnetic resonance spectra (1H-NMR, 13C-NMR), as well as the heteronuclear single quantum coherence (HSQC), and by conducting a heteronuclear multiple bond coherence (HMBC) experiment. Infrared (IR) spectroscopy and high-resolution mass spectrometry (HRMS) were also performed. Additionally, pharmacokinetic parameters and drug similarity of the studied molecule were calculated using in silico methods.
