Traces of water as a key parameter for the formation of an epoxydithio compound

The presence of a small amount of water has proven to be necessary in order to obtain a reproducible amount of an epoxydithio compound. Conversely, under anhydrous conditions, an interesting thiosugar derivative results from a selective internal attack of sulfur, followed by an 'ethyl' transfer. Georg Thieme Verlag Stuttgart.

Selective synthesis of α-C-(alkynyl)-galactosides by an efficient tandem reaction

Several α-C-(alkynyl)-galactosides were synthesized using a tandem reaction involving the addition of a metal alkynylide to a chiral acyclic epoxyaldehyde, followed by an in situ closure of the generated alkoxide on the epoxide function.
