86% | With titanium(IV) tetraethanolate In toluene at 110℃; for 1.5h; Molecular sieve; | General procedure: A single-necked flask equipped with a reflux condenser and an argon inlet system was charged with related tri-O-benzyl-pentofuranose, 4 Å activated molecular sieves (0.4 g per mmol of substrate) and(S)- or (R)-2-methyl-2-propanesulfinamide (2.0 equiv.). Dry toluene (4 mL per mmol of substrate) was inserted and the mixture was stirred for 5 min at room temperature (~20 °C). Titanium(IV) ethoxide (Ti(OEt)4, 1.5 equiv.) was then added and the reaction mixture was stirred at 110 °C until no more starting material was observed by TLC (generally,1.5 h). The content was next allowed to reach 20 °C and NaBH4 (4.0 equiv.) was added. The resulting suspension was stirred at 110 °C until no more sulfinyl glycosylamine intermediate remained in the reaction mixture (1 h). The suspension was then allowed to cool down to room temperature and sat. aqueous NaCl was added. The mixture was stirred at 20 °C for 10 min and the precipitate and molecular sieves were filtered through a pad of Celite. The cake was rinsed (EtOAc) and the aqueous layer was discarded. The organic phase was washed (sat. aq.NH4Cl), dried over MgSO4, filtered through a cotton plug and concentrated in vacuo. The crude product was purified through column chromatography (SiO2, PE:EtOAc) to provide the 1-N-tert-butanesulfinylamino-1-deoxy-pentitol derivative. |
