amino acids. In this article, the asymmetric aldol-reduction reaction leading to 1,3-diols (known as the aldol–Tishchenko reaction) has been performed with an elaborated family of ligands. This unique tandem reaction was catalysed by chiral Yb complexes that promote both the aldolreaction of unactivated carbonyl compounds and the Evans–Tishchenko reduction of the aldol intermediates. 1,3-anti-Diols with
The present invention relates to compounds that are antagonists of the orexin-1 receptor. The compounds have the structural formula (I) defined herein. The present invention also relates to processes for the preparation of these compounds, to pharmaceutical compositions comprising them, and to their use in the treatment of diseases or disorders associated with orexin-1 receptor activity.
The present invention relates to acyclic piperazine and piperidine derivatives, which are especially useful for treating or preventing neuronal damage, particularly damage associated with neurological diseases. These compounds are also useful for stimulating nerve growth. The invention also provides compositions comprising the compounds of the present invention and methods of utilizing those compositions for treating or preventing neuronal damage or for stimulating nerve growth.
