NEW DRUGS COMPRISING 2,3-OR 3,4-DIPHENYL DERIVATIVES OF YPSILON-NITRILE-ESTERS OR THE CYCLIZATION PRODUCTS THEREOF,NEW 2,3-AND 3,4-DIPHENYL DERIVATIVES OF YPSILON-NITRILE-ESTERS AND CYCLIZATION PRODUCTS AND PROCESSES FOR PREPARING THEM

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.
