摘要

New drugs comprising 2,3- or 3,4-diphenyl derivatives of gamma -nitrile-esters or the products of cyclization of the 2,3-diphenyl derivatives according to the formulae A, B and C are claimed. Process for cyclization of 2,3-diphenyl derivatives of gamma -nitrile-esters, new 2,3-diphenyl derivatives of gamma -nitrile-esters corresponding to the formulae I to VIII are claimed; new 3,4-diphenyl derivatives of the said esters coresponding to the formulae IX and X, and new 3,4-diphenylpiperidone derivatives corresponding to the specific formulae IX to XXVII are described.
