Abstract
Process for obtaining dibenzocycloheptene derivatives, and especially for the preparation of a compound of formula ** (See formula) ** where the dashed line indicates that the compound may be saturated or unsaturated in the indicated position; X, X 'are each hydrogen, levyalkyl, levialkoxy, levyalkenyl, halolevialkenyl, phenyl, substituted phenyl, an acyl group of up to 4 carbon atoms, a haloacyl group of up to 4 carbon atoms, amino, levialkylamino, dilevyalkylamino, a group acylamino of up to 4 carbon atoms, a haloacylamino group of up to 4 carbon atoms; levyalkylsulfonylamino, halogen, hydroxyl, halolevialkoxyl, cyano, carboxyl, carbamyl, levyalkylcarbamyl, dilevialkoxyl, alkylmercapto, halolevialkylmercapto, levyalkylsulfonyl, halolevialkylsulfonyl, sulfamyl, levialkylsulfamyl or dilevialkylsulfamyl; each benzenoid ring may contain more than one of these substitutes; and Y is hydrogen or a halogen; which comprises the reaction of a compound of formula ** (See formula) ** where X and X 'are as before, or Y is hydrogen or a halogen, with an allylmagnesium halide, to obtain a compound of formula ** (See formula) ** where X, X 'and Y are as before; the dehydration of this to form the corresponding diene of formula ** (See formula) ** where X, X 'and Y are as before; and the hydroboration of the latter to form the corresponding 5- γ -hydroxypropylidene derivative.
