摘要
A method for selective reaction of 1-aryl-propane-1-ones with 1,2-dihydrxy grop of D-mannitol in the presence of ZnCl2-BF3 Et2O to 1, 2_O-(1-aryl- propylidene )-D-mannitol (1-4 ) is described. The compounds were first reported and determined by IR, MS, 1H-/13C-NMR spectra.among them the Shae of 1 was further defined by X-ray diffraction
