Enantioselective Synthesis of Dihydrospiro[indoline-3,4'-pyrano[2,3-c]pyrazole] Derivatives via Michael/Hemiketalization Reaction.
TL;DR: A new bifunctional squaramide organocatalyst derived from L-proline mediated the first enantioselective synthesis of dihydrospiro[indoline-3,4'-pyrano[2,3-c]pyrazole] derivatives in excellent enantiOSElectivity by reacting pyrazolones with isatylidine β,γ-unsaturated α-ketoester.
Journal ArticleDOI
Palladium Catalyzed Asymmetric Allylation of 3-OBoc-Oxindoles: An Efficient Synthesis of 3-Allyl-3-hydroxyoxindoles
TL;DR: 3-Allyl-3-hydroxyoxindoles were synthesized in very good enantio- and diastereoselectivities with contiguous quaternary and tertiary stereogenic centers by employing tartrate derived bi(oxazoline) in Pd-catalyzed allylation of 3-OBoc-oxindole.
Journal ArticleDOI

Subramaniam Muthusamy,Nandarapu Kumarswamyreddy,Venkitasamy Kesavan,Srinivasan Chandrasekaran +3 more
TL;DR: The use of molecular oxygen as an oxidant is certainly environmental friendly and adds to the greenness of the process as mentioned in this paper, and a number of metal catalysts have been developed for aerobic oxidation.
Journal ArticleDOI
Stereoselective and Regioselective Assembly of Spirooxindole [2,1‐b]furan Motifs through a Tandem Friedel–Crafts Alkylation/5‐exo‐dig‐Cyclization
TL;DR: 3-Alkynyl-3-OBoc (Boc = tert-butoxycarbonyl) oxindole derivatives underwent a CuII-mediated stereo- and regioselective Friedel–Crafts alkylation/5-exo-dig-cyclization with 2-naphthols or cyclic 1,3-diketones, which gave spirooxindole [2,1-b]furan motifs in good to
Journal ArticleDOI
Assembly of 3-allyl-3-ethynyl-oxindole motifs via palladium(II)-catalyzed quaternary allylation of 3-ethynyl-3-OBoc-oxindoles
TL;DR: Palladium(II)-catalyzed C3-allylation of 3-ethynyl-3-OBoc oxindole derivatives was achieved for the first time to access highly functionalized 3-allyl-2-ethylene substituted oxindoles derivatives for a broad range of substrates in very good yields.
