Abstract

Procedure for the synthesis of (±) - glaziovina, of formula **(See formula)** characterized in that it comprises the operations of: (a) reacting a compound of the formula **(See formula)** where -OR represents an easily hydrolyzable ether or ester group chosen from the following: methoxymethoxy, tetrahydropyranyloxy, benzyloxy, trityloxy, acetoxy, trifluoroacetoxy, methanesulfonyloxy, ethoxycarbonyloxy, phenoxycarbonyloxy and their analogs, with a reagent chosen from the reactant halogens, nitrosating and nitrating agents and their derivatives, to obtain an 8-derived compound of the formula **(See formula)** where Y represents a halogen, or one of the following groups: **(See formula)** (b) transform this derivative into a 4'-hydroxy-8-substituted compound of formula **(See formula)** and finally (c) transforming the 4'-hydroxy-8-substituted compound, under the addition of ultraviolet radiation or by heating, into the (±) - glaziovina.
