Ni-catalyzed domino transformation of enopyranoses and 2-iodo phenols/anilines to pyrano cis fused dihydro-benzofurans/indoles.

A Ni-catalyzed direct access to various pyrano cis-fused dihydro benzofurans and indoles from unsaturated enopyranoses and o-iodo phenols/anilines is developed. The domino synthesis of pyrano C2-C1 and C3-C2 cis-fused heteroarynes were achieved both from glycals and pseudo glycals in which heteroatoms are linked at C2 and C3 positions, respectively, with excellent chemo-selectivity.
