- Mechanochemical synthesis of primary amides from carboxylic acids using TCT/NH4SCN
-
A facile and effective approach toward the synthesis of primary amides from carboxylic acids has been developed. In the presence of 2,4,6-trichloro-1,3,5-triazine, a combination of ammonium thiocyanate and potassium carbonate led to the rapid conversion of carboxylic acids into the corresponding amides within five minutes grinding at room temperature. The use of ammonium thiocyanate as the amine source is unprecedented and exclusive formation of primary amides is observed only under the liquid-assisted grinding conditions.

- Sodium azide as a catalyst for the hydration of nitriles to primary amides in water
-
The selective conversion of aromatic nitriles to primary amides has been accomplished using sodium azide. The corresponding amides were obtained efficiently in excellent yields. This reaction was carried out under eco-friendly conditions using water in the absence of organic solvents.

- Pd(OAc)2-catalyzed lactonization of arylacetamides involving oxidation of C-H bonds
-
The reaction of arylacetamides that contain a quinolin-8-ylmethylamine as the directing group with PhI(OAc)2, in the presence of Pd(OAc)2 as the catalyst, results in lactonization to give γ-lactones, the formation of which involves activation of the ortho C-H bonds, with concomitant cleavage of the directing group.

- Novel 3-azaindolyl-4-arylmaleimides exhibiting potent antiangiogenic efficacy, protein kinase inhibition, and antiproliferative activity
-
Tumor growth and metastasis are highly associated with the overexpression of protein kinases (PKs) regulating cell growth, apoptosis resistance, and prolonged cell survival. This study describes novel azaindolyl-maleimides with significant inhibition of PKs, such as VEGFR, FLT-3, and GSK-3β which are related to carcinogenesis. Furthermore, these compounds exhibit high kinase selectivity and potent inhibition of angiogenesis and cell proliferation, offering versatile options in cancer treatment strategies.
