Trifluoroacetic Acid-Promoted Synthesis of 3-Hydroxy, 3-Amino and Spirooxindoles from α-Keto-N-Anilides
摘要:
Ketoanilides containing alkyl side chains were readily cyclized to 3-hydroxy-2-oxindoles or spirooxindoles by a single or double intramolecular Friedel-Crafts reaction in the presence of trifluoroacetic acid (TFA) at room temperature or at 45 degrees C. alpha-Iminocarboxamides, generated in situ from ketoamides, cyclized similarly to 3-aminooxindoles under identical conditions,
The present invention relates generally to compositions and methods for treating cancer and neoplastic disease. Provided herein are substituted pyrrolopyridine derivative compounds and pharmaceutical compositions comprising said compounds. The subject compounds and compositions are useful for inhibition of histone demethylase. Furthermore, the subject compounds and compositions are useful for the treatment of cancer, such as prostate cancer, breast cancer, bladder cancer, lung cancer and/or melanoma and the like.
Easily Accessible Auxiliary for Palladium-Catalyzed Intramolecular Amination of C(sp<sup>2</sup>)H and C(sp<sup>3</sup>)H Bonds at δ- and ε-Positions
for selectiveCH activation under palladium catalysis. The novel auxiliary showed its first powerful application in CH functionalization of remote positions. Both C(sp2)H and C(sp3)Hbonds at δ‐ and ε‐positions were effectively activated, thus giving tetrahydroquinolines, benzomorpholines, pyrrolidines, and indolines in moderate to excellent yields by palladium‐catalyzed intramolecular CH amination
