Procédé de préparation de composés d'intérêt par cyclisation intramoléculaire et formation d'un pont éther biaryl

Novel method for intermolecular cyclization by formation of a biaryl ether bridge through the reaction as shown above. In formulas (I) and (II) R1 is a nitro radical adjacent to the oxygen bridge, Hal is a fluoride or chlorine atom, R2, R3 and R4 together form a peptidic chain, in the presence of a weak phase in a heterogeneous medium. The invention also concerns compounds of formulas (I) and (II) and the use of compounds of formula (I) to obtain useful compounds.
