The synthesis of some condensed indolizinediones derived from pyroglutamic acid is described. Treatment of these ketones in HCl, HBr or MeONa/MeOH furnished aryl propionic acid derivatives. During the ketone transformations, two sequential processes could take place in competitive manner to provide heterocyclic systems bearing carboxylic acid or hydroxycarboxylic acid function.

Tetrahydro-M-4 and tetrahydro-IsoM-4 are new compounds which may be prepared by the catalytic hydrogenation of M-4 or IsoM-4 respectively. They, and their salts and esters (which may be prepared by conventional salification or esterification reactions with the parent tetrahydro-M-4 or tetrahydro-IsoM-4), are capable of inhibiting cholesterol biosynthesis in the liver and may be formulated, for therapeutic use, with conventional pharmaceutical carriers or diluents.
