Acid-catalyzed dehydration of the polyhydroxyalkyl chain of 6,6-dimethyl-2-(D-gluco-pentitol-1-yl)-4,5,6,7-tetrahydroindol-4-one and of 6,6-dimethyl-2-(D-manno-pentitol-1-yl)-4,5,6,7-tetrahydroindol-4-one gave 2-.alpha.-D-arabinofuranosyl-6,6-dimethyl-4,5,6,7-tetrahydroindol-4-one. Similarly, 2-.beta.-D-lyxopyranosyl-6,6-dimethyl-4,5,6,7-tetrahydroindol-4-one and 2-.beta.-D-lyxopyranoxyl-4,5,6,7-tetrahydroindol-4-one were obtained by dehydration of 6,6-dimethyl-2-(D-galacto-pentitol-1-yl)-4,5,6,7-tetrahydroindol-4-one and 2-(D-galacto-pentitol-1-yl)-4,5,6,7-tetrahydroindol-4-one, respectively. The structures of the new C-nucleosides described were elucidated by chemical and physical methods.
