of enantiopure 4‐oxy‐substituted 3‐aminopyrrolidines arising from the enantioselective ring‐opening of meso‐3‐pyrroline oxide have been developed as catalysts for the asymmetric, anti‐selective Mannichreaction (see scheme; PMP=p‐methoxyphenyl; PG=protecting group). Very high catalytic activity (down to 0.01 mol % loading) and stereoselectivity have been recorded.
The invention relates to compounds of formula (I) wherein U, V, W, X, R1, R2, R3, R4, R5, R6, A, B, D, E, G, m, and n are as defined in the description, to pharmaceutically acceptable salts of such compounds for use in the manufacture of a medicament for the prevention or treatment of a bacterial infection. Certain compounds of formula (I) are new and are also part of this invention.

The synthesis of novel tricyclic 1,2,3-triazoles starting from cyclic epoxides via the sequential azidolysis, propargylation and 1,3-dipolar cycloaddition is described. Derivatization by N-arylation reaction and the synthesis of enantiomerically pure compounds is also reported. Some of these compounds exhibit significant affinity for the sigma-1 receptor.
