abstract: This study was designed to inform the renaming of a credit-bearing information literacy course. Researchers surveyed librarians to gather existing information literacy course titles. They also surveyed and held focus groups with students to learn what students consider when choosing electives, to understand how well the researchers’ current information literacy course title fits the course content, and to procure suggestions for a new title. Findings indicate that course titles are one of many elements that students look at when selecting courses. Some librarian and student participa

The asymmetric unit of the title compound, C16H24Cl2O2, contains two independent molecules (AandB) which are built from three fused rings,viz.a seven-membered heptane ring, a six-membered cyclohexyl ring bearing a ketone and an alcohol group, and a cyclopropane ring bearing two Cl atoms. In the crystal, the two molecules are linkedviatwo O—H...O hydrogen bonds, forming anA–Bdimer with anR22(10) ring motif. TheAmolecules of these dimers are linkedviaa C—H...O hydrogen bond, forming chains propagating along thea-axis direction. Both molecules have the same absolute configuration,i.e.1S,3R,8R,10S

The hetero-Diels–Alder reaction is the main synthetic tool for obtaining pharmacological agents with a thiopyrano[2,3-d]thiazole motif. In the present work, an efficient method for the synthesis of pyrazoline-containing thiopyrano[2,3-d]thiazole is described.
