What are the synthesis methods of 1- [5- (2,6-difluorophenyl) -4,5-dihydro-1,2-oxazole-3-yl] ethyl ketone?

To prepare 1 - [5- (2,6-diethylphenyl) -4,5-dihydro-1,2-oxazole-3-yl] acetonitrile, the synthesis method is as follows:

First, key intermediates can be constructed through a series of organic reactions. For the aryl moiety, the coupling reaction of suitable halogenated aromatics with diethylphenyl-containing reagents under the catalysis of transition metals, such as the Suzuki coupling catalyzed by palladium or the Ullmann reaction catalyzed by copper, can introduce 2,6-diethylphenyl. This step requires precise regulation of the reaction conditions to ensure that the reaction is efficient and selective. Solvent selection, base type and temperature control are all crucial.

When constructing an oxazole ring, raw materials containing nitrogen and oxygen atoms can be used with carbonyl compounds, which can be condensed and cyclized under acid or base catalysis. If a suitable amino alcohol is reacted with an acid chloride or an acid anhydride, the oxazole ring structure is formed through the molecular inner pass ring. During the reaction process, attention should be paid to the proportion of raw materials and the reaction sequence to prevent side reactions from occurring, such as avoiding the formation of polymers or other cyclized isomers.

When introducing the acetonitrile part, a nucleophilic substitution reaction can be used. The obtained oxazole ring-containing intermediate reacts with halogenated acetonitrile under basic conditions, so that the halogen atom is replaced, thereby connecting the acetonitrile group. In this step, the reaction temperature and the strength of the base should be controlled to prevent unnecessary reactions in oxazole ring opening or other parts.

In the whole synthesis route, strict separation and purification are required after each step, and high-purity intermediates and target products are obtained by means of column chromatography and recrystallization. The optimization of the reaction conditions of each step needs to be finely adjusted according to the characteristics of the substrate, the reaction mechanism and the actual experimental results to achieve the efficient synthesis of 1 - [5- (2,6-diethylphenyl) -4,5-dihydro-1,2-oxazole-3-yl] acetonitrile.
