Fig. 2: Substrate scope for 3-OH and 2-OH selectivity.
From: Carbene-catalyzed chirality-controlled site-selective acylation of saccharides

The ratios referred to acylation on 2-OH:3-OH and were determined by 1H NMR. aReactions were performed at 0 °C. bReactions were performed at r.t. cIt was also synthesized by other methods to verify our results (see Supplementary Information 4.2).
