To prepare 4- (2,2-diethyl-1,3-naphthalene-heterocyclopentene dioxide-4-yl) -1H-pyrrole-3-acetic acid, the following methods can be used.
One is the method of nucleophilic substitution. First, take the naphthalene-heterocyclopentene dioxide halide containing the appropriate substituent, and the nucleophilic reagent containing the pyrrole structure, in a suitable solvent, such as N, N-dimethylformamide (DMF) or dimethyl sulfoxide (DMSO), under the catalysis of a base, such as potassium carbonate or sodium carbonate, the nucleophilic substitution reaction occurs between the two to form a key intermediate. This intermediate is then suitably carboxylated, such as with carbon dioxide under specific conditions, or with halogenated acetate after hydrolysis, to obtain the target product.
The second is the way of cyclization reaction. The chain compound with the appropriate functional group is used as the starting material, and the prototype of the naphthalene and heterocyclopentene dioxide part and pyrrole ring is constructed through a series of reactions. For example, the functional groups interact with each other through an intra-molecular ring-closing reaction. The commonly used reaction conditions depend on the characteristics of the raw materials, or involve acidic or basic catalysts, which promote cyclization under conditions such as heating. After cyclization, the resulting product is suitably modified, and an acetic acid group is introduced to achieve the synthesis of the target product.
The third is the method of using transition metal catalysis. Select suitable transition metal catalysts, such as palladium, copper, etc., to catalyze the coupling reaction of substrates containing different functional groups. For example, in the presence of transition metal catalysts and ligands, in the presence of transition metal catalysts and ligands, in the presence of suitable solvents and bases, the coupling reaction occurs between halides containing naphthalene and heterocyclopentene dioxide and compounds containing pyrrole and acetate precursors, and the target product 4 - (2,2 - diethyl - 1,3 - naphthalene and heterocyclopentene dioxide - 4 - yl) - 1H - pyrrole - 3 - acetic acid is obtained directly or after several steps of conversion. Each method has its own advantages and disadvantages, and the actual operation needs to be comprehensively selected according to factors such as the availability of raw materials, cost and difficulty of reaction conditions.
