摘要:
The present invention relates to novel substituted phenyl compounds of the formula and to a process for making them. The compounds can be used as intermediates for making 6-substituted-1-(2H)-isoquinolinone derivatives.

Tetracyclic antibiotics and processes for their preparation .beta.-Lactam antibiotics of the formula I, and their pharmaceutically tolerable salts ##STR1## where X is (CH.sub.2).sub.0-2, CR(a)R(b), O, SO.sub.0-2 or NR(c),R1, R2 and R3 are a multiplicity of substituents, are outstanding antibiotics with remarkably good antibacterial activity both against gram-positive and against gram-negative microorganisms. They have a high stability to renal dehydropeptidase.They are obtained by cyclization of the compounds II ##STR2## or III ##STR3##
