Abstract

Procedure for the preparation of asymmetric bifunctional cyclopropanic derivatives, particularly of a compound of formula I: **(See formula)** in which: X is a carboxy, carbamoyl, carbamoyl radical N mono or disubstituted by an alkoyl or carbamimidoyl radical, a cyano, formyl, hydroxymethyl, hydroxymethyl (alkoxy substituted), aminomethyl, carbamoyloxymethyl N radical mono or disubstituted by an R radical or a carbamoyl radical, an R-oxymethyl or acyloxymethyl radical; R1, R2, R3, R, which may be the same and different, represent a hydrogen atom, a lower alkoyl, lower alkenyl, lower alkynyl radical, a phenyl radical or a mono, di or tricyclic aromatic group comprising 5 or 6 links and from 0 to 4 heteroatoms; R'1, R'2, R'3, which may be the same or different, represent a hydrogen atom or a lower alkoyl radical; as well as the esters and the Bales of the preceding acids and alcohols and the oximes of the preceding ketones, characterized in that a ketone is reacted under conditions such that it forms a carbanion of formula II: **(See formula)** on an epichlorohydrin derivative of formula III: **(See formula)** the substituents R1, R2, R3, R'1, R'2, R'3 having in the formulas II and III the same meaning as in the formula I and R'4 being a hydrogen atom or an alkoyl radical, and by which then treats the alcohol function of the keto-alcohol obtained to obtain a compound of formula I.
