Paragraph 0015; 0072; 0074, (2022/01/04)
The present invention relates to a preparation method and application of a molecular motor containing oxidized benzofuran structure, belonging to the field of organic chemistry technology. The first motor is based on 3-methyl-2,3-dihydrofyl-4(1H)-ketone and 2-coumarinone as raw materials, the second motor is based on 3-methyl-2,3-dihydrophenanthrene-4(1H)-keto and naphthalene [1,2-b]furan-2(3H)-ketone as raw materials, the third motor with 3-methyl-2,3-dihydrophenanthin-4 (1H)-keto and 6-isopropylphenone-2(3H)-keto as raw materials, in the presence of titanium tetrachloride and 1,8-diazoacyclodo-unicyclic-7-ene, In anhydrous tetrahydrofuran solvents, nucleophilic addition reactions are prepared. The reaction conditions of the present invention are mild, there is no need to add strong acids and strong bases, the equipment requirements are low, the operating cost is reduced; the reaction process produces less waste, the degree of environmental pollution is low; the obtained product motor structure is novel and has potential application value in the field of molecular devices.

In this Communication, procedures for the selective synthesis of 4-arylbutanoic acids, 2-arylbutanoic acids, and 4-arylbutanals from the same allylbenzenes have been developed. With formic acid or TFBen as the CO surrogate, reactions proceed selectively and effectively under carbon monoxide gas-free conditions.
