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 .
