Crystal Structure and Physicochemical Characteristics of Two Novel Adamantane Derivatives of Sulfonamides

Abstract: Two derivatives of adamantane benzenesulfamide have been synthesized and studied: N-adamantane-1-yl-2,4,6-trimethyl-benzenesulfamide (1) and N-adamantane-1-yl-4-methoxy-benzenesulfamide (2). Crystal structures 1 and 2 are solved using X-ray diffraction (XRD) analysis. The solubilities of compounds in a phosphate buffer solution with pH 7.4, 1-octanol, and n-hexane are determined at several temperature points using isothermal saturation. The values of Gibbs energy, enthalpy, and entropy of solubility of the compounds at 298 K are determined. © 2021, Pleiades Publishing, Inc.
