Direct preparation of 2-deoxy-d-glucopyranosides from glucals without ferrier rearrangement
TLDR
In this paper, an efficient catalytic procedure for the preparation of 2-deoxyglucosides from glucals without allylic or Ferrier rearrangement using triphenylphosphine hydrobromide and a wide variety of hydroxylic nucleophiles is described.Abstract:

Chapter 12 The invention of the alkynol cycloisomerization reaction: Application to the synthesis of digitoxin
TL;DR: In this paper, an endo-regioselective "alkynol cycloisomerization" process was proposed for the synthesis of various cyclic enol ethers including possibly glycals, if a reaction that is compatible with a variety of functional groups can be developed.

Total syntheses of caloundrin B and its putative precursor, and their transformations into siphonarin B, baconipyrone A, and baconipyrone C
TL;DR: Caloundrin B cannot be an isolation artifact and must be considered a plausible biosynthetic product from which the in vitro formation of siphonarin B, baconipyrone A, baconIPyrone C can be readily explained.

Armed-Disarmed Concept in the Synthesis of Glycosidic Bond
TL;DR: The authors showed that n-pentenyl glycosides undergo chemospecific cleavage 1 → 2 → 3, with N-bromosuccinimide under condition that leave a wide variety of other protecting groups unaffected.
