A novel tandem ferrier rearrangement-cyclisation. Synthesis of chiral pyrano[2,3-b][1]benzophyran system.

Tetrahedron Letters

A simple and convenient method for the synthesis of aryl-3,4,6-tri-O-benzyl-2-deoxy-2-methylene-hexopyranosides 5,6 and 7, glycosides which are not accessible by the conventional Ferrier rearrangement, has been described based on the Mitsunobu reaction of alcohols 3 and 4 with substituted phenols. The anomeric configurations of glycosides 5 and 6 were established by detailed NOE studies. The reaction is also successfully extended to the synthesis of phthaloyl derivative 10. A mild, neutral and non-acidic alternative to Ferrier rearrangement for the synthesis of 2,3-dideoxy-hex-2-enopyranosides has also been demonstrated with a variety of nucleophiles. © 1994.
