Design and synthesis of 4-benzylpiperidine carboxamides as dual serotonin and norepinephrine reuptake inhibitors
摘要:
A series of 4-benzylpiperidine carboxamides were designed and synthesized, and tested for their dual (serotonin and norepinephrine) reuptake inhibition. The synthesis of 4-benzylpiperidine carboxamides involved two main steps: amidation and substitution. Derivatives with 3 carbon linker displayed better activity than with 2 carbon linker. 4-Biphenyl- and 2-naphthyl-substituted derivatives 7e and 7j showed greater dual reuptake inhibition than standard drug venlafaxine HCl.

hydrocarbons have been investigated at room temperature under deaerated conditions. Secondary amide such as N-(2-chloroethyl)-2-naphthamide (CENA) or N-(2-bromoethyl)-2-naphthamide (BENA) was obtained along with a rearranged product of 2-(2-naphthyl)-2-oxazoline (NOz). The initial rate of secondary amide formation increased with decreasing dissociation energy of the carbon–halogen bond of halogenated

Photo-induced Ring-opening Reactions of 1-(2-Naphthoyl)aziridine in Various Solvents
Photoreactions of 1-(2-naphthoyl)aziridine (NAz) have been investigated in various solvents under the deaerated conditions at room temperature. The photo-irradiation of NAz in halogenated hydrocarbons afforded halogen substituted secondary amides such as N-(2-chloroethyl)-2-naphthamide (CENA) or N-(2-bromoethyl)-2-naphthamide (BENA), a ring-expanded isomer of 2-(2-naphthyl)-2-oxazoline (NOz) and the NAz
