Die Umsetzung von Aminosäure-N-carbonsäure-anhydriden (1) (Oxazolidindionen-(2.5)) mit N-silylierten Aminen führt nicht wie dieReaktionmitAminen zu Oligo- oder Polypeptiden. Als Reaktionsprodukte entstehen N-Trimethylsiloxycarbonyl-aminosäure-amide (2) neben Hydantoinsäure-silylestern (12), die nach Hydrolyse als Aminosäureamide (4) und Hydantoinsäuren (5) isoliert wurden. Die Umsetzung N-silylierter

The present invention relates to novel hydroxyethylamine compounds having Asp2 (β-secretase, BACE1 or Memapsin) inhibitory activity, processes for their preparation, to compositions containing them and to their use in the treatment of diseases characterised by elevated β-amyloid levels or β-amyloid deposits, particularly Alzheimer's disease.

The present invention relates to chemokine receptor binding compounds, pharmaceutical compositions and their use. More specifically, the present invention relates to modulators of chemokine receptor activity, preferably modulators of CCR4 or CCR5. In one aspect, these compounds demonstrate protective effects against infection of target cells by a human immunodeficiency virus (HIV).
