Abstract

Summary D-Sorbitol, in solution with 4 N hydrochloric acid and one molecular equivalent of benzaldehyde, condenses to yield principally a cryptocrystalline dibenzyli# ene-D-sorbitol melting at 219-221'. The latter substance, upon oxidation with lead tetraacetate in glacial acetic acid, produces formaldehyde and aldehydo-2, 3, 4, 5-dibenzylidene-~-xylose, which is conveniently isolated as a crystalline methyl hemiacetal. This hemiacetal is converted ...
