Several 5-0-toluene-p-sulphonyl and 5-iodo derivatives of «-and 3-ribofuranoses and «-xylofuranose have been prepared in order to study their reactions with sodium hydrogen carbonate in dimethyl sulphoxide. Similar reactions are known to convert acylic primary sulphonates and iodides to aldehydes...

Catechols are important precursors in the production of pharmaceuticals but they are associated with many problems such as their instability and susceptibility to oxidation and polymerisation. In order to avoid these problems, acylcatechols are used. However, disadvantages exist in the industrial...
