Description

Method for synthesizing 1, 4-naphthoquinone cyclopropane compound
Technical Field
The invention relates to a synthesis method of an organic compound, in particular to a preparation method for synthesizing a 1, 4-naphthoquinone cyclopropane compound.
Background
1, 4-naphthoquinone has wide application in the aspects of dyes, organic medical intermediates and the like due to the unique properties of the naphthoquinone, and becomes a hot spot. In industrial production, 1, 4-naphthoquinone is an important raw material in fine chemical engineering, is widely applied to intermediates of dyes, medicines, perfumes, pesticides, plasticizers and the like, is a polymerization regulator for synthesizing rubber and resin, and is an important substance for synthesizing novel papermaking cooking aids, for example, 1, 4-naphthoquinone is an important intermediate for synthesizing naphthoquinone dyes and derivatives thereof, anthraquinone, tetrahydroanthraquinone, high-purity 1-aminoanthraquinone and antitumor drugs, is a raw material for synthesizing 2, 3-dihydro-1, 4-anthraquinone series dyes, and can be used as a polymerization regulator, a curing agent for photochemical cross-linked polyester, a corrosion inhibitor, a stabilizer for transformer oil, synthetic flame-retardant polyester and the like. Meanwhile, 1, 4-naphthoquinone compounds are small molecular compounds widely existing in nature and have various biological activities, for example, many derivatives of 1, 4-naphthoquinone have good bactericidal, medical and biological properties, such as antimalarial activity, and researches show that 5-hydroxy-1, 4-naphthoquinone has hemostatic and antibacterial activities and is used for treating eczema, tinea manuum and tinea pedis; the derivative of 2-hydroxy-1, 4-naphthoquinone is effective inhibitor for tumor cell respiration, and its bridged complex has wide application. Due to the wide application range, the method for efficiently and environmentally synthesizing the 1, 4-naphthoquinone is very important to find. The synthesis of naphthoquinone has been reported at home and abroad, for example, chromium trioxide is used as an oxidant to oxidize polycyclic aromatic hydrocarbon containing side chains under an acidic condition, but the method has a complex process, high cost for producing 1, 4-naphthoquinone and certain limitation; furthermore, a liquid phase oxidation method of naphthalene is adopted, high-valence heavy metal salt is used for indirect electrolytic oxidation, and HNO is used3,H2O2,IO4 -,S2O4 2-The method for preparing naphthoquinone by oxidizing nonmetal oxides has the disadvantages of high energy consumption, difficult naphthoquinone separation, more reaction byproducts and great pollution.
In addition, cyclopropane structures are widely present in natural products and drug molecules and have good biological activity. For example, the sponge extract (1) has an antitumor activity, the pyrethroid (2) has an insecticidal activity, and the like. Meanwhile, cyclopropane structures belong to the smallest cyclic structures, and the backbone thereof has a rigid planar structure and a specific bond angle, and can construct a plurality of chiral centers, and thus have recently been receiving attention from chemists.

The cyclopropane compound not only has various biological activities, but also is a key intermediate for synthesizing a plurality of pesticides and drug molecules, so the research on the synthesis method of the cyclopropane compound has important significance and is a hotspot in the field of organic chemistry. There are also many conventional methods for synthesizing cyclopropane compounds, for example, Freund's reaction (3), ylide cyclopropanation (4), carbene cyclopropanation (5), and the like. However, the traditional synthesis method has a lot of disadvantages, equivalent metallic sodium is needed in the Freund reaction, and the operation process has certain dangerousness; the ylide cyclopropanation reaction can generate a large amount of waste, and the atom utilization rate is very low; the carbene cyclopropanation reaction synthesizes cyclopropane compounds through the [2+1] cyclization reaction of olefin and active intermediate carbene, and the method also has the defect of low atom utilization rate.

Aiming at the defects of the traditional cyclopropane compound synthesis, the recent Kazuhiko Takai and the like utilize olefin and I2CHB(OR)2Synthesis of borocyclopropane compounds under the catalysis of chromium chloride [ see org. Lett.,2017,19(22), pp 6104-6107-]However, the method needs to add 6 times of equivalent of chromium dichloride, and a large amount of metal waste is generated after the reaction, which is not beneficial to industrial production.
Compared with the traditional synthesis method for synthesizing the 1, 4-naphthoquinone and the cyclopropane compound, the synthesis method disclosed by the patent has great advantages, the method related to the patent can be used for synthesizing the 1, 4-naphthoquinone cyclopropane compound in one step by adopting a one-pot method under mild conditions, the steps are simple, the efficiency is higher, and the method has a greater prospect in the aspect of industrial application.
