hydroxyalkyl functions can be arylated usingaryl or heteroaryl bromides, via palladium‐catalysed carbon‐hydrogen bond activation/arylation. Good yields were generally obtained using 0.01–0.5 mol% of the air‐stable palladium acetate complex as the catalyst. The nature of the base was found to be crucial for the selectivity of this reaction. Potassium acetate led to the direct arylation products whereas caesium
The invention relates to novel compounds that have S1P receptor modulating activity. Further, the invention relates to a pharmaceutical comprising at least one compound of the invention for the treatment of diseases and/or conditions caused by or associated with inappropriate S1P receptor modulating activity or expression, for example, autoimmune response. A further aspect of the invention relates to the use of a pharmaceutical comprising at least one compound of the invention for the manufacture of a medicament for the treatment of diseases and/or conditions caused by or associated with inappropriate S1P receptor modulating activity or expression such as autoimmune response.
