  Aryl radical cyclizations onto enamine double bonds

  摘要：

  Aryl radicals from N-alkyl-N-(2-bromobenzyl)-1-cyclohexenylamine 2 and N-alkyl-N-(2-bromobenzyl)-cyclopentenylamine 11 cyclize readily onto the enamine double bond by 6-endo and 5-exo closure. In the case of 2, 6-endo cyclization is the major pathway; however, the 6-endo to 5-exo ratio is dependent upon the N-alkyl substituent. In both cases, the dominant isomer from 6-endo cyclization is the cis isomer. For 2a in toluene, values of k6-endo and k5-exo at 80-degrees-C were 4.6 X 10(8) s-1 and 1.5 x 10(8) s-1, respectively.

  Benzylamines: synthesis and evaluation of antimycobacterial properties

  摘要：

  The synthesis of benzylamines with various N-alkyl chains and substituents in the aromatic system as well as their evaluation on Mycobacterium tuberculosis H 37 Ra are described. The most active compounds in this test, N-methyl-3-chlorobenzylamine (19, MIC 10.2 micrograms/mL), N-methyl-3,5-dichlorobenzylamine (93, MIC 10.2 micrograms/mL), and N-butyl-3,5-difluorobenzylamine (103, MIC 6.4 micrograms/mL), also exhibited a marked inhibitory effect on Mycobacterium marinum and Mycobacterium lufu used for the determination of antileprotic properties. The combinations of 93 with aminosalicylic acid, streptomycin, or dapsone exert marked supra-additive effects on M. tuberculosis H 37 Ra.

  method for carbonylation of aromatic and heteroatomatic halides is described. The catalytic system consists of a combination of alkylcobalt carbonyl complexes, either preformed or made “in situ”, and bases such as alkoxides, NaOH and K2CO3 in aliphatic alcohols. Under these conditions new anionic cobalt complexes are formed which are characterized by a very high reactivity towards aromatic halides. The latter

• Design, synthesis and biological evaluation of ambenonium derivatives as AChE inhibitors

  Ambenonium (1), an old AChE inhibitor, is endowed with an outstanding affinity and a peculiar mechanism of action that, taken together, make it a very promising pharmacological tool for the treatment of Alzheimer's disease (AD). Unfortunately, the bisquaternary structure of 1 prevents its passage through the blood brain barrier. In a search of centrally active ambenonium derivatives, we planned to synthesize tertiary amines of 1, such as 2 and 3. In addition, to add new insights into the binding mechanism of the inhibitor, we designed constrained analogues of ambenonium by incorporating the diamine functions into cyclic moieties (4-12). The biological evaluation of the new compounds has been assessed in vitro against human AChE and BChE. All tertiary amine derivatives resulted more than 1000-fold less potent than 1 and, unlike prototype, did not show any selectivity between the two enzymes. This result, because of recent findings concerning the role of BChE in AD, makes our compounds, endowed with a well-balanced profile of AChE/BChE inhibition, valuable candidates for further development. To better clarify the interactions that account for the high affinity of 1, docking simulations and molecular dynamics studies on the AChE-1 complex were also carried out.
