In the absence of catalysts, the three-component, one-pot synthesis of α-aminonitriles proceeded using various aldehydes and ketones together with amines and trimethylsilyl cyanide (TMSCN) in high yields under neat conditions at room temperature. The addition order of the reagents had a significant influence on the yields of the desired α-aminonitriles. In contrast, when tin ion-exchanged montmorillonite

N-aryl-N-[1-furyl(thienyl)but-3-enyl]amines (homoallylamines) or 2-(N-arylmethylamino)-2-furyl(thienyl)acetonitriles (α-aminonitriles) were easily prepared in good to excellent yields by an indium-mediated Barbier-type reaction between N-hetarylaldimines and allyl bromide in MeOH or a direct three component reaction between anilines, hetaryl aldehydes and trimethylsilyl cyanide in the presence of a catalytic amount

The present application provides novel kynurenine pathway inhibitors and pharmaceutically acceptable salts and prodrugs thereof. Also provided are methods for preparing these compounds. These compounds are useful in regulating the kynurenine pathway and the activity of indoleamine 2,3-dioxygenase and/or tryptophan 2,3-dioxygenase by administering a therapeutically effective amount of one or more of the compounds of formula (I) to a patient. By doing so, these compounds are effective in treating conditions associated with the dysregulation of the kynurenine pathway. A variety of conditions can be treated using these compounds and include diseases which are characterized by immunosuppression, abnormal cellular proliferation and/or inflammation. In one embodiment, the disease is cancer. In another embodiment, the disease is a viral infection. In a further embodiment, the disease is depression.

hetaryl fragments were easily prepared from corresponding aldimines derived from commercially available aromatic aldehydes and anilines. 2-Furyl substituted anilines showed very good antifungal activities against dermatophytes, particularly against Trichophyton rubrum (MIC=3.12-6.25microg/mL). In addition, all active compounds, 45-47, 73, and 74, were tested for cytotoxic activities against breast (MCF-7)
