Method for synthesizing 4-fluorocyclohexanone
-
Paragraph 0100-0105, (2018/05/16)
The invention discloses a method for synthesizing 4-fluorocyclohexanone. The method comprises steps as follows: under the alkaline condition, 1,4-cyclohexanedione monoethylene ketal and a fluorinatingagent are subjected to highly selective reaction, and 8-fluoro-1,4-dioxaspiro[4.5]deca-7-ene is produced; 8-fluoro-1,4-dioxaspiro[4.5]decane is prepared from 8-fluoro-1,4-dioxaspiro[4.5]deca-7-ene and hydrogen under the action of a palladium-carbon catalyst; 8-fluoro-1,4-dioxaspiro[4.5]decane is subjected to deprotection with added acid, and 4-fluorocyclohexanone is obtained. According to the method, 1,4-cyclohexanedione monoethylene ketal which is widely sourced and low in cost is taken as a reaction raw material, a high-purity intermediate can be obtained maximumly in each reaction, so thatthe total yield of the whole reaction is high, purity of a final product is up to 98%, the economic benefit is quite remarkable, less environmental pollution is produced, and the method is particularly suitable for large-scale industrial application and popularization.
NOVEL BENZAMIDE DERIVATIVE AND USE THEREOF
-
Paragraph 0122-0124, (2014/10/16)
Disclosed are a novel benzamide derivative and pharmaceutical use thereof, and more particularly, a novel benzamide derivative having a structure of Formula 1 or pharmaceutically acceptable salts thereof, and a composition for prevention or treatment of pain or itching including the above material. The novel benzamide derivative and pharmaceutically acceptable salt thereof according to the present invention exhibit excellent pain-suppressive effect and, in particular, pain-suppressive effect in not only a neuropathic animal model but also other models such as a formalin model, and therefore, may be used in suppression of different pains such as nociceptive pain, chronic pain, etc. Further, since it was demonstrated that the present invention displays anti-pruritic efficacy even in an itching model, to which a mechanism and treatment concept established with respect to pain is applied, the present invention may also be effectively used in radical treatment of atopic dermatitis by applying the inventive product to an anti-pruritic composition in order to suppress an initial itching stage and treat symptoms thereof, thus preventing skin damage or inflammation after the scratching stage.
