Abstract

A process for preparing 4,6,6-trimethyl-2,4,5,6-tetrahydrocyclopenta [c] pyrrole-4-carboxamides of formula I, **(See formula)** in which: one of the symbols R1 and R3 is hydrogen or lower alkyl, and the other is a group of the formula: **(See formula)** in which: R5 is hydrogen; and R6 is phenyl, lower alkenyl, cyano, lower alkyl, lower alkynyl, carbo-lower alkoxy-lower alkylene or carbo-lower alkoxy-lower alkynyl; and R2 is lower alkyl or phenyl; characterized by reacting a corresponding compound of formula I, in which one of the symbols R1 and R3 is formyl, with an organic lithium or with an organic magnesium halide corresponding to R6, and hydrolyzing the resulting organometallic compound.
