quaternary centres from ketones via the diborylation process and Suzuki–Miyaura cross-coupling reaction. This methodology, which simultaneously introduces two different kinds of electrophilic structures, exhibits a large substrate scope and high functional group tolerance. The reaction products with aldehyde and allylic groups have proved to be versatile synthons to prepare complex molecules crucial for natural
The present invention relates to compounds of formula I
wherein Ar1, Ar2, Ar3, n, and
R1 to R8 are as defined herein and to pharmaceutically suitable acid addition salts, optically pure enantiomers, racemates or diastereomeric mixtures thereof. These compounds are orexin receptor antagonists and may be useful in the treatment of disorders, in which orexin pathways are involved, like sleep disorders.

catalyst-controlled route to prostaglandin F2α and its analogues. The approach uses a Rh-catalyzed dynamic kinetic asymmetric Suzuki–Miyaura coupling reaction between a racemic bicyclic allyl chloride and alkenyl boronic esters bearing chiral alcohols to give cyclopentyl intermediates bearing 3 contiguous stereocenters. The route provides advancedintermediates in 99% ee as a single diastereoisomer in all cases
