A General Catalytic Route to Enantioenriched Isoindolinones and Phthalides: Application in the Synthesis of (S)-PD 172938
TL;DR: A concise synthesis of ( S)-PD 172938 has been demonstrated by using this protocol, and a variety of enantioenriched isoindolinones and phthalides containing α-diazoesters were afforded in excellent yields.
Journal ArticleDOI
Silica gel induced cleavage of aziridines by aromatic amines under solvent free conditions
TL;DR: A variety of aziridines were opened in an efficient manner with aromatic amines using silica gel under solvent free conditions as mentioned in this paper, where the amine amines were formed by a mixture of amine derivatives.
Journal ArticleDOI
DDQ as a Mild and Efficient Catalyst for Deprotection of Tetrahydropyranyl Ethers
Sushil Raina,Vinod K. Singh +1 more
TL;DR: In the presence of a catalytic amount of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ), tetrahydropyranyl ethers are readily hydrolysed to their corresponding alcohols in wet acetonitrile under mild conditions.
Journal ArticleDOI
Ag(I)-Catalyzed Indolization/C3-Functionalization Cascade of 2-Ethynylanilines via Ring Opening of Donor-Acceptor Cyclopropanes.
TL;DR: A AgSbF6-catalyzed cascade involving the ring opening of donor-acceptor cyclopropanes (DACs) preceded by the cyclization of N-protected 2-ethynylaniline is described, revealing a step-economy route to 2,3-disubstituted indole, where a Ag catalyst is found to trigger the cascade by activating both alkyne and DACs.
Journal ArticleDOI
Bifunctional chiral urea catalyzed highly enantioselective Michael addition of cyclic 1,3-dicarbonyl compounds to 2-enoylpyridines
TL;DR: In this article, a cinchona alkaloid based bifunctional urea catalyzed enantioselective conjugate addition of cyclic 1,3-dicarbonyl compounds to a range of β-substituted 2-enoylpyridines has been developed.
