The Shapiro reaction of acetophenone is the key in a convenient three-step access to a divinyl ketone which is further transformed by double aza-Michael reactions with primary amines into N-substituted 3-phenyl-4-piperidones. In the case of N-benzyl and N

A series of new κ opioid receptor (KOR) agonists were developed from the lead compound 4-dimethylamino-1-pentanoylpiperidine (3), a matrine-type alkaloid. Derivatives of 3 were synthesized with a variety of phenyl substituents and evaluated for their anti

We synthesized a series of novel 3-phenyl-4-benzylaminopiperidine derivatives that were identified as potent tachykinin NK1 receptor antagonists by structural modification of the 3-benzhydrylpiperidone derivative through high-throughput screening. N-{2-[(3R,4S)-4-({2-Methoxy-5-[5-(trifluoromethyl)- 1Htetrazol-1-yl]benzyl}amino)-3-phenyl-1-piperidinyl]-2-oxoethyl}acetamide ((+)-39) was found to be one of the most potent tachykinin NK1 receptor antagonists with high metabolic stability. Highly efficient asymmetric synthesis of (+)-39 was achieved via dynamic kinetic resolution.
