Bhardwaj, Monika; Rasool, Bisma; Mukherjee, Debaraj published an article in 2022, the title of the article was Ni-catalyzed domino transformation of enopyranoses and 2-iodo phenols/anilines to pyrano cis fused dihydro-benzofurans/indoles.Name: (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate And the article contains the following content:
A Ni-catalyzed direct access to various pyrano cis-fused dihydro benzofurans and indoles, e.g. I (R1 = MeCO, PhCO; X = O, R2 = H, Me, t-Bu; X = NH, R2 = H), from unsaturated enopyranoses, e.g. II, and o-iodo phenols/anilines, e.g. III, is developed. The domino synthesis of pyrano C2-C1 and C3-C2 cis-fused heteroarynes was achieved both from glycals and pseudo glycals, in which heteroatoms are linked at C2 and C3 positions, resp., with excellent chemo-selectivity. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Name: (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate
The Article related to pyrano cis fused dihydro benzofuran indole preparation stereoselective chemoselective, enopyranose iodo phenol aniline nickel catalyst domino heterocyclization, Heterocyclic Compounds (More Than One Hetero Atom): Fused-Ring Systems With Two Or More Hetero Atoms, No More Than One Hetero Atom Per Ring and other aspects.Name: (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate
