标 题:Partial synthesis process for preparing (+) -vincamine and related indolic alkaloids
发明人：BENARDELLI GIOVANNI
权利人:LINNEA SA
摘要:A process of partial synthesis of vincamine and related indolic alkaloids for use as the active principal ingredient in drugs for treatment of diseases of the circulatory system and the central nervous system. The process includes the technique of activating oxygen in the elementary state in situ into an excited singlet state for chemical reaction by subjecting a reaction mixture to gaseous oxygen blowing under substantially ambient temperature and pressure conditions while effecting irradiation of the mixture by a light source. Operating conditions of the partial synthesis process are simplified, treatment times are reduced, and conversion yields are high.

标题 :Process for synthesizing halogenated derivatives of fluorescein for use in the production of non-volatile memory devices
发明人：VOLPE MARIA VIVIANA; CIMMINO ANGELA; PEZZELLA ALESSANDRO; PALMA ANIELLO
权利人:ST MICROELECTRONICS SRL
摘要:A process performs solid phase synthesis of halogenated derivatives of fluorescein, and includes reacting fluorescein with a halide MX, wherein M is an alkali metal and X is a halogen, and Oxone® (2 KHSO 5 .KHSO 4 .K 2 SO 4 ), at a temperature higher than or equal to 150° C. A structure uses a halogenated derivative of fluorescein selected from the group consisting of 2′,4′,5′-trichlorofluorescein, 2′,4′,5′,7′-tetrachlorofluorescein, 4′,5′-diiodofluorescein diacetate and 2′,4′,5′-triiodofluorescein as electro-bistable material in a non-volatile memory device.

标 题 :Multiplex synthesis method of compound library and parallel synthesizer of compound library using same
发明人：KIM DONG PYO; AHN GWANG NOH
权利人:POSTECH RES & BUSINESS DEV FOUND
摘要:The present invention relates to a parallel synthesis method and synthesizer of a compound library, and more specifically provides a parallel synthesis method and synthesizer of a compound library, which uniformly distribute a first reactant and perform independent reactions in separate spaces, and since it is possible to confirm the results for various reaction variables at once, the synthesis time of the compound library can be reduced with a high synthesis yield of the product.
