## Abstract This paper describes the synthesis of some 5βaminoβ1,2,3,4βtetrahydrobenzo[__b__][1,7]naphthyridines and 2,3,4,4a,5,6βhexahydrobenzo[__c__][2,6] naphthyridines starting from anilines and 1βbenzylβ4βethoxycarbonylpiperidinβ3βone. The compounds were prepared in order to study their potent
Z-Substituted-1,2,3,4,5,6-hexahydro-3-bemwxine-4, 6diones(la-d) and 2-methoxy-2,5,6,7-tetrahydro+ benxamnine-1,3dione 8 were synthesii thro@ an oxklative ring expansion reaction of 6-methylthio-7-substiituted-benzo(a] octem (2a-d ) and 7-methylthio%-methoxy-benzo[a]nonem 7 with sodium periodate in i
