Abstract: The stereoselective allylations of β-amino-α-hydroxy aldehydes are described. Several Lewis acids (BF3·OEt2, SnCl4, TiCl4, ZnCl2, and MgBr2·OEt2) were utilized in the allylations. The allylation of anti-β-NHCbz-α-OTBS substrate mediated by SnCl4 afforded the syn-selective product, while… read more here.
