Open-chain acetonides of D-galactono-1,4-lactone as starting materials for pyrrolidines, azepanes and 5-azidomethyltetrahydrofuran-2-carboxylates: monomers for polyhydroxylated nylon and for tetrahydrofuran carbopeptoids
Treatment of D-gaIactono-l,4-lactone with dimethoxypropane in acetone in the presence of tosic acid forms methyl 2,3:5,6-di-0-isopropylidene-D-galactonate 6 (with only the secondary hydroxy group at C-4 unprotected) and methyl 2,3:4,5-di-O-isopropyIidene-D-galactonate 5 (with only the primary hydrox...
