Abstract: Deoxygenation of a secondary hydroxy group on β-cyclodextrin was conducted to prepare the title compound 2II-VII, 3I-VII, 6I-VII-icosa-O-acetyl-2I-deoxy-cyclomaltoheptaose. The synthetic procedure comprised a two-step reaction—phenoxythiocarbonylation and Barton-McCombie deoxygenation. The synthesized compound was characterized by 1H-NMR, 13C-NMR, HRMS, and elemental analysis.

Abstract: The title compound, (E)-3-methyl-6-(3-oxo-3-(thiophen-2-yl)-1-propenyl)-2(3H)-benzothiazolone, was synthesized by Claisen-Schmidt condensation of 3-methyl-2(3H)-benzothiazolone-6-carbaldehyde with 2-acetylthiophene in 94% yield. The structure of the target compound was confirmed using 1H-NMR, 13C-NMR, IR, MS, and elemental analysis.
