Synthesis method of (2S, 3S)-3-(t-butyloxycarboryl amino)-1, 2-epoxy-4-phenylbutane

The invention relates to the technical field of synthesis of drug intermediates, in particular to a synthesis method of (2S, 3S)-3-(t-butyloxycarboryl amino)-1, 2-epoxy-4-phenylbutane. The method comprises the following steps: condensing N-t-butyloxycarboryl-L-phenylalanine serving as a raw material with substituted phenol under the action of a condensing agent to obtain active ester 15; reacting the active ester 15 with a ylide reagent and alkali to obtain a sulfoxide ylide intermediate 16; reacting the sulfoxide ylide intermediate 16 with halide salt under the action of a catalyst to obtain a halogenated ketone intermediate 6; reducing the halogenated ketone intermediate 6 through a reducing agent under the action of a catalyst to obtain a halogenated methanol intermediate 7; and removing halogen acid from the halogenated methanol intermediate 7 under the action of alkali, and carrying out condensation cyclization to obtain the target product (2S, 3S)-3-(t-butyloxycarboryl amino)-1, 2-epoxy-4-phenylbutane. The synthesis method of the (2S, 3S)-3-(t-butyloxycarboryl amino)-1, 2-epoxy-4-phenylbutane, provided by the invention, has the characteristics of cheap and easily available initial raw materials, safe and controllable process and easiness in operation.

Merging N-Hydroxyphthalimide into Metal-Organic Frameworks for Highly Efficient and Environmentally Benign Aerobic Oxidation

Two highly efficient metal-organic framework catalysts TJU-68-NHPI and TJU-68-NDHPI have been successfully synthesized through solvothermal reactions of which the frameworks are merged with N-hydroxyphthalimide (NHPI) units, resulting in the decoration of pore surfaces with highly active nitroxyl catalytic sites. When t-butyl nitrite (TBN) is used as co-catalyst, the as-synthesized MOFs are demonstrated to be highly efficient and recyclable catalysts for a novel three-phase heterogeneous oxidation of activated C?H bond of primary and secondary alcohols, and benzyl compounds under mild conditions. Based on the high efficiency and selectivity, an environmentally benign system with good sustainability, mild conditions, simple work-up procedure has been established for practical oxidation of a wide range of substrates.

Continuous production method of benzoic acid derivative

The invention relates to the technical field of preparation of benzoic acid derivatives. The invention particularly relates to a continuous production method of a benzoic acid derivative. The continuous reaction device is characterized by comprising a small-diameter sleeve, wherein the small-diameter sleeve is sleeved with a large-diameter sleeve, and a small pipeline is arranged between the small-diameter sleeve and the large-diameter sleeve, and a plurality of small holes are arranged on the small pipeline. The small-diameter casing is rotated, the large-diameter casing is fixed, and the reaction liquid composed of the nitric acid and the toluene derivative is between a small-diameter casing pipe and a large-diameter casing pipe.
