| Abstract: | Acid-catalyzed acetonation of d-glycero-d-galacto-heptose yields solely the 1,2:3,4:6,7-tri-O-isopropylidene pyranoid derivative, whereas d-glycero-l-gluco- and d-glycero-l-manno-heptose react in the furanose form to give 1,2:5,6-(major) and 1,2:6,7-di-O-isopropylidene-d-glycero-l-gluco-heptose (minor), and 2,3:5,6-(major) and 2,3:6,7-di-O-isopropylidene-d-glycero-l-manno-heptose (minor), respectively. |
