The invention provides novel compounds having the general formula (I) and tautomers and pharmaceutically acceptable salts thereof, wherein A1, A2, A3, A4, R1, R4, R5, R6, R7 and R8 are as defined herein, compositions including the compounds and methods of using the compounds.
The reaction of dialkyl acetals derived from α,β-unsaturated aldehydes with Grignard reagents using TiCl4in THF afforded the cross coupling products, allyl ethers, in high yields. The TiCl4-promotedreaction of alkyl 2,4-dichlorophenyl acetals, synthesized from 3,4-dihydro-2H-pyran or ethyl vinyl ether and 2,4-dichlorophenol, with Grignard reagents in THF at low temperature afforded the corresponding
