Deoxygenation/dimerization of sugar derivatives with BF3·Et2O–Et3SiH: synthesis of a β-isonucleoside
Publikováno v:
Tetrahedron Letters. 53:4929-4932
Lewis acid-Et 3 SiH induced deoxygenation of anomeric carbon of sugars generates tetrahydrofuran derivatives, accompanied by hitherto unknown dimeric products. If the reagent addition steps are reversed, tetrahydrofuran derivatives are obtained as th

In 1-deoxy-xylofuranose derivatives possessing a good leaving group at 2-C, participation of allyloxy and propargyloxy substituents at 5-C results in loss of the 2-C substituent and attack of various nucleophiles at 5-C of the oxonium intermediate. S

S-Alkenyl and -alkynyl carbohydrate derivatives were prepared from 1,2:5,6-O-diisopropylidene-α-D-allofuranose. Nitrones and nitrile oxides generated from these derivatives led to the formation of 6, 7, and 11-membered chiral sulfur heterocycles fus
