| Abstract: | The sodium salt of TOSMIC reacted with (E)-3,4,5,6,7-penta-O-acetyl-1,2-dideoxy-1-C-nitro-D-galacto- (1) and -D-manno-hept-1-enitol (2) to give 3-(D-galacto- (3) and 3-(D-manno-penta-O-acetylpentitol-1-yl)-4-nitropyrrole (4) , respectively. Compound 1 reacted with diaryl nitrile imines, affording 1,3-diaryl-4-(1,2,3,4,5-penta-O-acetyl-D-galacto-pentitol-1-yl)pyrazoles 5 and 6 . |
