Synthesis of pyrrolidines and pyrrolidinones by the rhodium complex catalyzed cyclization of unsaturated amines
摘要:
N-Allylic arylamines react with carbon monoxide, sodium borohydride, 2-propanol, and catalytic amounts of the zwitterionic complex eta-6-C6H6BPh3-Rh(COD)+ (1), to form pyrrolidines as the main products in most cases. Pyrrolidinones result from N-allylic alkylamines. An alternate route to the lactams from N-allylic alkylamines involves synthesis gas instead of CO/NaBH4, together with the dual catalytic system 1/[Ru(CO)3Cl2]2. Complementary to the N-allylic arylamine route to pyrrolidines with NaBH4 and 1 is the use of synthesis gas, 1, and 1,4-bis(diphenylphosphino)butane.
Provided is an agent for treating or preventing urinary frequency, urinary urgency and urinary, incontinence which are associated with overactive bladder, a lower urinary tract disease such as interstitial cystitis and chronic prostatitis accompanied by lower urinary tract pain, and various diseases accompanied by pain. A novel azolecarboxamide derivative in which an azole ring such as thioazole or oxazole is bonded to a benzene ring, pyridine ring or pyrimidine ring through carboxamide was confirmed to have a potent trkA receptor-inhibitory activity and found to be an agent for treating or preventing lower urinary tract disease and various diseases accompanied by pain, which is excellent in efficacy and safety, and thus the present invention was accomplished.
