2′-Hydroxy-fendiline analogues as potent relaxers of isolated arteries
Novel, 2′-hydroxy derivatives of fendiline have been synthesised and their ability to induce relaxation of isolated rat small mesenteric and coronary arteries were determined. Both derivatives examined were significantly more potent as vasodilators than f
Chiral Fe(ii) complex catalyzed enantioselective [1,3] O-to-C rearrangement of alkyl vinyl ethers and synthesis of chromanols and beyond
A highly efficient enantioselective [1,3] O-to-C rearrangement of racemic vinyl ethers that operates under mild conditions was developed. This method with chiral ferrous complex catalyst provided an efficient access to a wide range of chromanols with high yields and excellent enantioselectivities. In addition, an important urological drug (R)-tolterodine and others were easily obtained after simple transformations.
Heteroatom-Guided, Palladium-Catalyzed, Site-Selective C-H Arylation of 4H-Chromenes: Diastereoselective Assembly of the Core Structure of Myristinin B through Dual C-H Functionalization
A highly site-selective, heteroatom-guided, palladium-catalyzed direct arylation of 4H-chromenes is reported. The C-H functionalization is driven not only by the substituents and structure of the substrate but also by the coupling partner being used. The diastereoselective assembly of the core structure of Myristinin B has been achieved by using a dual C-H functionalization strategy for regioselective direct arylation.
