Zusammenfassung: | The invention discloses a synthetic method of 5-hydroxymethyl furfural doped 2,3-unsaturated glucoside. The synthetic method is characterized in that a Ferrier rearrangement reaction is carried out on D-fructose in dimethyl sulfoxide by taking FeCl3 6H2O/C as a catalyst, prepared 5-hydroxymethyl furfural is not separated and is directly used as a receptor in the next Ferrier rearrangement reaction, and a one-pot reaction is carried out on the receptor and 2,3-unsaturated saccharides which are used as a donor to synthetize 2,3-unsaturated glucoside. Compared with the prior art, the synthetic method disclosed by the invention has the advantages that two reactions are used as the one-pot reaction to synthetize the 2,3-unsaturated glucoside, cyclic utilization of the catalyst is up to at least three times, the catalyst still has relative high catalytic activity, the technology is simple, the operation is convenient, the yield is high, the production cost is low, and the synthetic method is an environment-friendly |
