Stereoselectivity in Electrophile-Mediated Intramolecular Cyclizations of Hept-2-enitols

Electrophile (dibromine, diiodine, benzeneselenenyl chloride, and mercuric acetate) mediated intramolecular cyclization of (Z)-7-O-benzyl-1,2,3-trideoxy-4,5-O-isopropylidene-D-ribo-hept-2-enitol (9) gives predominantly 2,5-anhydro-1-O-benzyl-6,7-dideoxy-6

ELECTROPHILE-MEDIATED CYCLIZATIONS IN CARBOHYDRATE CHEMISTRY: SYNTHESYS OF HIGHLY FUNCTIONALIZED RIBOFURANOSE AND RIBOPYRANOSE COMPOUNDS

Iodine-mediated cyclization of (Z)- and (E)-D-ribohept-2-enonates 1 and 2 gave exclusively the β-ribofuranose and α-ribofuranose derivatives 3 and 4, respectively.Cyclization of the (Z)- and (E)-2-heptene-1-ol derivatives 5 and 6 gave ribofuranose product
