experimental part, p. 6092 - 6099 (2011/11/29)
A series of stable chiral C1-symmetric dinitrogen ligands were conveniently synthesized in high yields by condensation of chiral amines [(-)-exo-bornylamine or (+)-(1S,2S,5R)-menthylamine] with various substituted imidazolecarbaldehydes. With the assistance of base, the ligand L1 in combination with CuCl2·2H2O (2.5 mol-% or 5.0 mol-%) can efficiently promote nitroaldol (Henry) reactions between a variety of aldehydes and nitromethane. Both aromatic and aliphatic aldehydes were tolerated in our catalytic system, affording the expected nitroalcohol products in high yields (up to 97%) and with good enantioselectivities (up to 96%) under mild reaction conditions.

A direct synthetic approach to novel quadrupolar [14]azolophanes
Alcalde, Ermitas,Alemany, Montserrat,Gisbert, Maria
, p. 15171 - 15188 (2007/10/03)
A convergent '3+1' synthesis allowed a simple entrance to the first examples of [14]metaazolophanes 1 and [14l(meta-ortho)2azolophanes 2 built up from heterocyclic betaine subunits, illustrating a prototype of phanes constructed by both highly π-excessiveand highly π-deficient heteroaromatic moieties linked in a 1,3-alternating fashion.
