✦ Synopsis

Careful analysis of the 1H and 13C NMR spectra of a series of isochromanylacetylarylhydrazone derivatives indicated the diastereomeric selective character in the synthetic step used to obtain the derivatives employing acidic conditions during the condensation of the corresponding acylhydrazides with functionalized arylaldehydes. The relative conÐguration at CxN was characterized by extensive 1H and 13C NMR experiments.

, COLOC] 2D shift-correlated spectra, along with 1D PND and DEPT 13C NMR and NOE di †erence spectra (1HM1HN NOE) were also used in this deduction.
