Document Language : English 
Abstract : The synthesis of naphtho[1,2-c]pyrazoline derivatives has been achieved via the condensation of 2-arylmethylidene-1-tetralones with hydrazine derivatives. 1H NMR nOe difference spectra and 2D-NOESY spectroscopic studies were employed to distinguish between the diastereotopic prochiral methylene protons HM and HN in 2-methyl-3-phenyl-3,3a,4,5-tetrahydronaphtho[1,2-c]pyrazole and proved that HJ and HM are down the plane and HH and HN are above the plane. These results revealed an anti relationship between the vicinal protons HH and HJ and confirmed this relative configuration of the two chiral centers in pyrazoline derivatives.
