Abstract

'Transitioning to online learning, educators have been tasked with the difficult work of finding ways to reimagine content and deliver engaging courses that best serve each student's learning journey. This work offers data-supported strategies for online chemistry education with perspectives from students, teaching associates, teaching fellows, and academics. Chapters include case studies around teaching chemistry online, a review of options for chemistry labs in an online course, and guidance for adapting on-ground chemistry courses for the virtual environment in both asynchronous and synchronous delivery modalities. This work is a valuable resource for chemistry instructors seeking to build authentic student engagement'--Publisher's description.

Abstract

4-Deoxypentenosides (4-DPs) are versatile synthons for rare or higher-order pyranosides, and they provide an entry for structural diversification at the C5 position. Previous studies have shown that 4-DPs undergo stereocontrolled DMDO oxidation; subsequent epoxide ring-openings with various nucleophiles can proceed with both anti or syn selectivity. Here, we report the synthesis of α- and β-linked 4'-deoxypentenosyl (4'-DP) disaccharides, and we investigate their post-glycosylational C5' additions using the DMDO oxidation/ring-opening sequence. The α-linked 4'-DP disaccharides were synthesized by coupling thiophenyl 4-DP donors with glycosyl acceptors using BSP/Tf2O activation, whereas β-linked 4'-DP disaccharides were generated by the decarboxylative elimination of glucuronyl disaccharides under microwave conditions. Both α- and β-linked 4'-DP disaccharides could be epoxidized with high stereoselectivity using DMDO. In some cases, the α-epoxypentenosides could be successfully converted into terminal l-iduronic acids via the syn addition of 2-furylzinc bromide. These studies support a novel approach to oligosaccharide synthesis, in which the stereochemical configuration of the terminal 4'-DP unit is established at a post-glycosylative stage.
