Abstract
(-)-7-Oxabicyclo[2.2.1]hept-5-en-2-one has been converted to (-)-6-exo-[(te rt-butyl)dimethylsilyloxy]-7-endo-benzyloxy-8-oxabicyclo[3.2.1]oct-3-en-2-o ne and methyl 3,5-di-O-acetyl-2,6-anhydro-4-O-benzoyl-D- glycero-D-galacto- heptouronate that were condensed with Me2AlSPh into a single aldol which wa s transformed into a beta-D-ManAp-CH(OAc)(1-->3)-alpha-L-GulAp-CH(SEt)(2) d erivative.
