摘要:The present invention provided a continuous flow process for the synthesis of phenylhydrazine salts and substituted phenylhydrazine salts. Diazotization, reduction, acidic hydrolysis and salifying with acids are innovatively integrated together. Using acidic liquids of aniline or substituted aniline, diazotization reagents, reductants and acids as raw materials, phenylhydrazine derivative salts is obtained through the synthesis process, which is a three-step continuous tandem reaction including diazotization, reduction, acidic hydrolysis and salifying. The described synthesis process is a kind of integrated solutions, which is carried out in an integrated reactor. The feed inlets of the integrated reactor are continuously filled with raw materials. In the integrated reactor, diazotization, reduction, acidic hydrolysis and salifying are carried out continuously and orderly, and phenylhydrazine salts or substituted phenylhydrazine salts is obtained in the outlet of the integrated reactor without interruption. The total reaction time is no more than 20 min.

摘要:A functionalized polycyclic compound can have a structure of Formula 1 or salt, prodrug, analog, or derivative thereof, which compound can be prepared by providing a diene; reacting the diene with a dienophile under sufficient conditions for a combined Diels-Alder/acylation reaction so as to provide a polycyclic compound having a carboxylic acid; and coupling the carboxylic acid with an amine-containing compound or a hydroxyl-containing compound so as to form an amide or an ester and producing a compound having a structure of Formula 1. The compound can be used for modulating an opioid receptor, which can be conducted by administering to an opioid receptor a functionalized polycyclic compound as described herein in an effective amount to modulate the functionality of the opioid receptor. Such opioid modulation can provide a biological benefit to a subject.

标题:Preparation of azo pigments with low pcb content by coupling in the presence of olefins
发明人：RIEPER WOLFGANG
权利人:HOECHST AG
摘要:The production which is customary in practice of monoazo compounds based on dichloro- and trichloroanilines or disazo compounds of the chlorinated biphenyl series by conventional coupling methods meets with difficulties in that the resulting pigments are contaminated by traces of polychlorinated biphenyls. n According to the invention, it has now been found that by addition of water-soluble olefins of the type ##STR1## (R =H, alk or Oalk; X =--COOR 1 , --CONHR 2 or --NR 3 COR 4 ) n in the azo coupling, the side reactions which form PCBs can be decidedly suppressed during synthesis of the pigments.
