ELECTROPHILE-MEDIATED CYCLIZATIONS OF 6-O-BENZYL-1,2-DIDEOXY-3,4-O-ISOPROPYLIDENE-D-ribo-HEX-1-ENITOL TO DERIVATIVES OF 2,5-ANHYDRO-6-O-BENZYL-3,4-O-ISOPROPYLIDENE-D-altro-HEXITOL

Electrophile (bromine, iodine, mercuric acetate, mercuric trifluoroacetate, phenylselenyl chloride)-mediated cyclization of 6-O-benzyl-1,2-dideoxy-3,4-O-isopropylidene-D-ribo-hex-1-enitol (2) led exclusively to 1-substituted derivatives of 2,5-anhydro-6-O
