The present invention relates to novel compounds which are inhibitors of CRAC channel activity. This invention also relates to pharmaceutical compositions containing them, process for their preparation and their use in therapy.
A new method has been developed for the construction of dihydrobenzofurans from O-aryloxime ethers bearing an alpha-cyano group using a sequential regioselective isomerization/[3,3]-sigmatropic rearrangement/cyclization reaction in MeOH without any catalysts under neutral conditions at ambient temperature. The current transformation provides environmentally benign and atom-economical access to a variety of dihydrobenzofurans containing a quaternary carbon from readily available cyclic and acyclic oxime ethers.
