Convenient synthesis of memantine analogues containing a chiral cyclopropane skeleton as a sigma-1 receptor agonist
摘要:
We have achieved a convenient enantioselective synthesis of memantine analogues containing a chiral cyclopropane skeleton as a sigma-1 receptor agonist in 19-40% overall chemical yields from the corresponding 2-arylbut-2-ene-1,4-diols with moderate to excellent asymmetric yields via regioselective acetylation using porcine pancreas lipase, catalytic enantioselective Simmons-Smith reactions, and amidation in aqueous organic solvent. This synthetic route is more efficient and less expensive than conventional methods. (C) 2016 Elsevier Ltd. All rights reserved.

The subject matter of the present invention is novel families of compounds which are aromatic amine, imine, aminoadamantane and benzodiazepine derivatives, medicaments comprising same and the use thereof as inhibitors of the toxic effects of toxins with intracellular activity, such as, for example, ricin, and of viruses that use the internalization pathway for infecting cells.

A novel method for the mono-N-alkylation of primary amines, diamines, and polyamines was developed using cesium bases in order to prepare secondaryamines efficiently. A cesium base not only promoted alkylation of primary amines but also suppressed overalkylations of the produced secondaryamines. Various amines, alkyl bromides, and alkyl sulfonates were examined, and the results demonstrated this

The nickel-catalyzed reduction of secondary and tertiary amides to give amine products is reported. The transformation is tolerant of extensive variation with respect to the amide substrate, proceeds in the presence of esters and epimerizable stereocenters, and can be used to achieve the reduction of lactams. Moreover, this methodology provides a simple tactic for accessing medicinally relevant α-deuterated
