The present invention relates to compounds having a pipecolate diketoamide scaffold, pharmaceutically acceptable salts of these compounds and pharmaceutical compositions containing at least one of these compounds together with pharmaceutically acceptable carrier, excipient and/or diluents. Said pipecolate diketoamide compounds can be used for prophylaxis and/or treatment of psychiatric disorders and neurodegenerative diseases, disorders and conditions.

[Cp*RuCl]4 catalyzes the addition of iPr3SiC≡CX (X = H, Cl) across internal alkynes with formation of 1,3-enyne or 1-chloro-1,3-enyne derivatives, respectively; the reaction follows an unorthodox trans-addition mode. The well-balanced affinities of the different reaction partners to the ruthenium catalyst ensure that crossed addition prevails over homodimerization of the individual components, as can
The synthesis of enantioenriched β-chlorohydrins is highly appealing due to their relevance as building-blocks in organicsynthesis. However, the approximation to aliphatic derivatives is particularly challenging due to the difficulties to get access to the α-chloroketone precursors. Herein, we propose a straightforward and scalable approach combining in a concurrent manner gold(I) and redox enzyme

Alkynyl chlorides were found to be extraordinarily novel electrophiles, which could afford a single regioisomer of the [3+2] annulation adducts with cyclic ketimines by rhodium catalysis. The alkenyl chloride moiety in the products provided a valuable functional handle for further diverse transformations. Therefore, this research provided not only a synthetic protocol for accessing unsymmetrically
