New sugar-derived bifunctional chiral ureas as highly effective organocatalysts in asymmetric aza-Henry reaction.

A simple synthesis of series of new catalysts derived from chiral bifunctional ureas is described. The aza-Henry reaction of imines with nitromethane was promoted by sugar derived bifunctional organocatalysts to give optically active β-nitroamines. The aza-Henry reaction products were obtained in good yields (35-98%) and ee up to 99%.

[Role of systemic consultation in the psychiatric diagnosis].

Basing on the example of one patient and her family, the advantages and disadvantages of a systemic consultation are presented. The patient was hospitalised due to schizophrenia. In the given example the psychiatrist was an observer of the consultation conducted by a therapist from the ward.
