Sulfated zirconia (SO4/ZrO2) as a reusable solid acid catalyst for the Mannich-type reaction between ketene silyl acetals and aldimines

Sainan Wang, MATSUMURA SHUICHI, Kazunobu Toshima

Tetrahedron Letters (Elsevier)  48 ( 37 ) 6449-6452 2007.09

Research paper (scientific journal), Joint Work, Accepted

　View Summary

Sulfated zirconia (SO4/ZrO2) catalyzed Mannich-type reaction of ketene silyl acetals and aldimines proceeded smoothly at room temperature to afford b-amino esters in good to high yields. In addition, the heterogeneous solid acid catalyst SO4/ZrO2 was easily recovered from the reaction mixture and then reused without significant loss of effectiveness.

Aryl C-glycosylation using an ionic liquid containing a protic acid

Chigusa Yamada, Kaname Sasaki, MATSUMURA SHUICHI, Kazunobu Toshima

Tetrahedron Letters (Elsevier)  48 ( 24 ) 4223-4227 2007.04

Research paper (scientific journal), Joint Work, Accepted

　View Summary

Aryl C-glycosylation of several glycosyl donors, including unprotected sugars, with phenol and naphthol derivatives in an ionic liquid containing a protic acid proceeded effectively and stereoselectively to give the corresponding aryl C-glycosides in good to high yields. Because the ionic liquid was nonvolatile, the reaction could be carried out under reduced pressure; in addition, the ionic liquid could be reused without loss of effectivelness. The features contribute to the significant advantages of this novel aryl C-glycosylation reaction.
