Fig. 2: UV spectrum and reaction condition screening.

From: Catalyst-free and wavelength-tuned glycosylation based on excited-state intramolecular proton transfer

Fig. 2

a UV-Vis spectrum of glycosyl donors 17 and 18. b UV-Vis spectrum of glycosyl donors 19 and 20. c UV-Vis spectrum of glycosyl donors 18 and 20. d Glycosylations using 17–21 as glycosyl donors and methanol as a glycosyl acceptor. e Model glycosylation reaction using 18 as a glycosyl donor and 1-adamantanol (24) as a glycosyl acceptor. Yields and diastereomeric ratios were determined by 1H NMR analysis using 1,3,5-trimethoxybenzene as an internal standard. M: mol/L.
