In this paper we report the synthesis and spectral analysis of new heterocyclic derivatives of 4-aryl thieno[3,2-c]pyridines. These functionalized compounds were obtained from heteroaromatic aldehyde derivative and a cyclisation via tandem aza-Wittig iminophosphorane reactions sequence. The assignment of the structures and conformation of the different derivatives were achieved using 1D and 2D NMR (NOESY, DEFT, HMQC and HMBC). (C) 1999 Elsevier Science B.V. All rights reserved.
