CONTROLLED FORMATION OF DIPYRANOSIDE DERIVATIVES THROUGH C6 AND 04. PYRANOSIDIC HOMOLOGATION. VII

A procedure has been developed for pyranosidic homologation of methyl α-D-glucopyranoside via C4 and C6.Reaction of the aldehydo group of compound 2 with the Wittig-Bestmann reagent, Ph3P=CHCH(OEt)2, gave an E/Z mixture of acetals, 4, which cyclizes under
