((1R,3aS,5aR,5bR,7aR,9S,11aR,11bR,13aR,13bR)-9-Acetoxy-5a,5b,8,8,11a-pentamethyl-1-(prop-1-en-2-yl)icosahydro-3aH-cyclopenta[a]chrysen-3a-yl)methyl 2-Bromo-3-methylbenzoate
In this report, we discuss the synthesis of modified betulin through the chemical derivatization of a natural compound. The compound was fully characterized by proton (1H), carbon-13 (13C), heteronuclear single quantum coherence (HSQC) and distortionless enhancement through polarization transfer (DEPT) NMR and elemental analysis. We investigated the optical properties through ultraviolet (UV) and Fourier-transform infrared (FTIR) spectroscopy.
