Novel unnatural dipeptoids useful as agents in the treatment of obesity, hypersecretion of gastric acid in the gut, gastrin-dependent tumors, or as antipsychotics are disclosed. Further, the compounds are antianxiety agents and antiulcer agents. The compounds are agents useful for preventing the response to withdrawal from chronic treatment or use of nicotine, diazepam, alcohol, cocaine, caffeine, and opioids. The compounds are also useful in treating and/or preventing panic attacks. Also disclosed are pharmaceutical compositions and methods of treatment using the dipeptoids as well as processes for preparing them and novel intermediates useful in their preparation. An additional feature of the invention is the use of the subject compounds to prepare diagnostic compositions.
asymmetric alkylation of aldehydes was studied, by using a homemade, custom-designed photoreactor for reactions under cryogenic conditions. Going from microfluidic conditions up to a 10 mL mesofluidic reactor, an increase of productivity by almost 18000 % compared to the batch reaction was demonstrated. Finally, for the first time, a stereoselective photoredox organocatalytic continuous flow reaction
通过使用自制、定制设计的光反应器在低温条件下进行反应,研究了醛的连续流动、对映选择性、有机光氧化还原催化不对称烷基化。从微流控条件到 10 mL 中流控反应器,与分批反应相比,生产率提高了近 18000%。最后,首次成功实现了在完全伸缩过程中用于活性药物成分 (API) 合成的立体选择性光氧化还原有机催化连续流动反应。最终工艺由四个操作单元组成:连续流动下可见光驱动的不对称催化苄基化、在线连续后处理、中和和最终的氧化酰胺化步骤,得到 95% ee 的药物活性分子

Ces composés peuvent en outre servir d'anxiolytiques et d'agents anti-ulcéreux. Ils sont utiles pour empêcher la réaction à l'arrêt d'un traitement chronique à la nicotine, au diazépam, à l'alcool, à la cocaïne, à la caféine et aux opioïdes ou d'un usage chronique de ces substances. Ces composés sont également utiles dans le traitement et/ou la prévention des crises de panique. La présente invention décrit aussi des compositions pharmaceutiques et des procédés de traitement qui utilisent ces dipeptoïdes, ainsi que des processus de préparation de ces dipeptoïdes et de nouveaux intermédiaires utiles dans leur préparation. Une autre caractéristique de la présente invention est l'utilisation de ces composés dans la préparation de compositions diagnostiques.
