Titanium-Mediated Spirocyclization Reactions of 4-Alkylpyridines
摘要:
Pyridines substituted at the 4-position with alkyl tethers containing beta-dicarbonyl moieties were converted to spirocyclic 4,4-disubstituted dihydropyridines. Optimal conditions for these transformations involved N-acylation of the pyridine substrate with a chloroformate electrophile in the presence of Ti((OPr)-Pr-i)(4). Cyclization products could be easily converted into spiro-piperidine derivatives or elaborated into more complex heterocyclic frameworks via Au-catalyzed cycloisomerization.

The present invention relates to tertiary amines of formula (I) for use in therapy, particularly for use in treating cardiovascular disorders. The compounds have been found to regulate phospholamban phosphorylation by interfering with the A-kinase anchor protein 18delta (AKAP185) binding to the PKA substrate phospholamban. The compounds share a tri(alkylaryl/alkylheteroaryl)amine structure.
