A series of alpha,alpha-diaryl-1-piperidinebutanols was evaluated for antiarrhythmicactivity in the coronary ligated dog model. Structure-activity relationship studies indicated that the 2,6-dimethylpiperidine group yielded compounds with the best antiarrhythmic profiles in this series. The length of the methylene chain separating the diarylcarbinol and the amino group was not crucial. Substitution

A class of tryptamine analogues bearing an optionally substituted phenyl nucleus at the 2-position are selective antagonists of the human 5-HT2A receptor and are therefore useful as pharmaceutical agents, especially in the treatment and/or prevention of adverse neurological conditions, including psychotic disorders such as schizophrenia.

iron-catalyzed method for the selective oxyfunctionalization of benzylic C(sp3)–H bonds in aliphatic amine substrates. This transformation is selective for benzylic C–H bonds that are remote (i.e., at least three carbons) from the amine functional group. High site selectivity is achieved by in situ protonation of the amine with trifluoroacetic acid, which deactivates more traditionally reactive C–H sites that are

N-(Methylcarbamoyl)-4-(dicyclohexylphosphino)-2-[(diphenylphosphino)methyl]pyrrolidine (MCCPM)- and N-(tert-butoxycarbonyl)-4-(dicyclohexylphosphino)-2-[(diphenylphosphino)methyl]pyrrolidine (BCPM)-rhodium(I) complexes werer efficient catalysts for asymmetric hydrogenations of β- and γ-amino ketone hydrochloride derivatives. Utilizing this methodology, we have developed efficient syntheses of fluoxetine and eprozinol from intermediate optically active amino alcohols.
