Co-reporter:Takahiro Soeta, Yuuki Kojima, Yutaka Ukaji, Katsuhiko Inomata
Tetrahedron Letters 2011 Volume 52(Issue 20) pp:2557-2559
Publication Date(Web):18 May 2011
DOI:10.1016/j.tetlet.2011.03.032
A first example of diphenylborinic acid catalyzed α-addition to isocyanide with aldehyde and water is described. The reaction proceeded smoothly in the presence of water and 5 mol % of borinic acid to give the corresponding α-hydroxyamides in good to high yields. A wide range of aldehydes and isocyanides are applicable to this reaction.

A new method for the highly effective synthesis of α-siloxyamides is described. The addition of isocyanide to aldehyde proceeded smoothly in the presence of silanol to give the corresponding α-siloxyamides in high yields. A wide range of aldehydes and isocyanides are applicable in this reaction.
