A new route of preparing 1,4-dihydro-3(2)-isoquinolinones and 5,6,7,8-tetrahydrolsoquinolinones was developed by the hydrogenation of 3(2)-isoquinolinones. The 1,4-dihydro compounds -, were also prepared by synthesis, when the - ratio significantly differed from that of the products obtained by hydrogenation. Relative configurations and site of conformational equilibria were established by n.O.e. difference
