Synthesis and Application of Bioactive N‐Functionalized Aziridines

Angewandte Chemie, EarlyView.
This review discusses modern synthetic methods for the preparation of aziridine‐containing small molecules, including biocatalytic, electrocatalytic, and photocatalytic strategies. We highlight the compatibility of various synthetic methods with control of the exocyclic N‐substituent.

Synthesis of Tricyclic Condensed Rings Incorporating the Pyrazole or Isoxazole Moieties Bonded to a 4-Piperidinyl Substituent

Molecules, 2013
In this paper we report the synthesis of new compounds based on the pyrazole and isoxazole framework fused to a cycloalkene unit, and bearing as a substituent the 1-piperidinyl group as new examples of potential antipsychotic molecules.

Synthesis of fused tricyclic amines unsubstituted at the ring-junction positions by a cascade condensation, cyclization, cycloaddition then decarbonylation strategy

Beilstein Journal of Organic Chemistry, 2012
Heating aldehydes that contain a protected hydroxymethyl group, a tethered alkyl chloride and a tethered alkenyl group at the α-position of the aldehyde with an amine sets up a cascade (tandem) reaction sequence involving condensation to an intermediate ...

Reductive Heck Reactions of N-Methyl-substituted Tricyclic Imides

Molecules, 2010
The palladium-catalyzed hydroarylation of N-methyl-substituted tricyclic imides was studied in order to find a new stereoselective access to a series of new exo-aryl(hetaryl)-substituted tricyclic N-methylimides.
