Non-peptide acetamide derivatives of Formula (I) are specific NK1 antagonists, where R is aryl, R?1 and R2¿ are H or alkyl, m, n and q are integers from 0 to 4, X is NR8 or NHCONH, R?3 and R9¿ are H or alkyl, R4 is naphthyl or indolyl, R?5 and R2¿ are H or alkyl, and R6 is aryl. The compounds are useful agents for treating inflammatory and allergic disorders, pain, anxiety, depression, schizophrenia and emesis.

An ammonium iodide/hydrogen peroxide-mediated intramolecular oxidative amination of 3-aminoalkyl-2-oxindoles was achieved, affording the corresponding 3,2'-pyrrolidinyl spirooxindoles and their 6- or 7-membered analogous in moderate to high yields. This metal-free procedure features very mild reaction conditions, non-toxicity and easily handled hydrogen peroxide as a clean oxidant.
