What are the synthesis methods of N- (1,3-benzodioxane-5-ylmethyl) -4-fluorobenzenesulfonamide?

To prepare N- (1,3-naphthaleno-dioxacyclopentene-5-ylmethyl) -4-bromo-naphthalenone, the following ancient method can be used.

First, starting with 1,3-naphthaleno-dioxacyclopentene-5-formaldehyde, the imine intermediate is obtained by condensation with a nitrogen-containing reagent. Then the imine is reduced with a suitable reducing agent, such as sodium borohydride, to obtain N- (1,3-naphthaleno-dioxacyclopentene-5-ylmethyl) amine. At the same time, using 4-bromo-naphthalidine as the substrate, under specific reaction conditions, a suitable functional group is introduced to make it have the activity to react with the above amines. Then, the two are mixed, and in the presence of a suitable solvent and base, a nucleophilic substitution reaction is performed, so that the target product can be obtained.

Second, 4-bromonaphthalidine can also be modified first to introduce a side chain containing an active group. This active group needs to be able to react with 1,3-naphthaleno-dioxane-5-ylmethyl. For example, a halogenation reaction can be used to bring a halogen atom to a specific position of 4-bromonaphthalidine to enhance its reactivity. At the same time, 1,3-naphthaleno-dioxane-5-ylmethyl is activated, for example, converted into a corresponding halogen or sulfonate. Subsequently, under the action of catalysts, such as palladium catalysts, the two are coupled to react to build the structure of the target molecule.

Furthermore, from the perspective of raw material selection, more convenient and easy-to-obtain starting materials can be sought. After multi-step reaction, the skeleton of the target product is gradually constructed. For example, starting with a compound with a partial target structure, the synthesis of the target molecule is gradually achieved through functional group transformation, cyclization and other reactions. During the reaction process, the reaction conditions, such as temperature, reaction time, and proportion of reactants, need to be carefully adjusted to ensure that the reaction proceeds in the expected direction and improve the purity and yield of the product. This synthesis method requires careful choice and careful handling according to actual conditions and needs.

What are the physical and chemical properties of N- (1,3-benzodioxane-5-ylmethyl) -4-fluorobenzenesulfonamide?

N- (1,3-benzodioxacyclopentene-5-methylbenzyl) -4-bromobenzamide is an organic compound. In terms of physical and chemical properties, let me tell you one by one.

Looking at its physical properties, under normal conditions, this compound is mostly solid. Because the molecular structure contains benzene rings, amide groups, etc., the intermolecular force is strong, and then the solid form is formed. Its melting point and boiling point are greatly affected by the intermolecular force and molecular structure. The presence of benzene rings enhances the rigidity of the molecule, and the amide group can form hydrogen bonds and increase the intermolecular force, so the melting point and boiling point are relatively high. However, the specific values need to be determined accurately by experiments.

In terms of solubility, this compound behaves differently in different solvents due to its polar amide group and non-polar benzene ring. In polar organic solvents such as methanol and ethanol, the amide group can form a hydrogen bond with the solvent, so it has a certain solubility; in non-polar organic solvents such as n-hexane, the solubility is poor due to the weak interaction between the molecule and the solvent.

In terms of its chemical properties, the amide group has a certain reactivity. Hydrolysis can occur. Under acidic or basic conditions, the amide bond breaks to form corresponding carboxylic acids and amines. Because there is a benzene ring in the molecule, it can carry out typical reactions of the benzene ring, such as electrophilic substitution reaction. Bromine atoms are attached to the benzene ring, which changes the electron cloud density of the benzene ring, and the electrophilic substitution reaction activity The structure of methyl benzyl and benzodioxane also affects the chemical properties of the whole molecule, or affects the activity and selectivity of the reaction check point.

In summary, the physicochemical properties of N- (1,3-benzodioxane-5-methylbenzyl) -4-bromobenzamide are determined by its molecular structure, and its application in organic synthesis and related fields is also based on these properties.
