Abstract
An electrochemical initiated tandem reaction of anilines with 2-formyl benzonitrile has been developed. Thus, unprecedented 3-N-aryl substituted isoindolinones have been conveniently achieved by constant current electrolysis in a divided cell using catalytic amount of electricity and supporting electrolyte and a Pt-cathode as working electrode. The origin of the electrochemical activation as well as the mechanism of the subsequent chemical cascade reactions have been investigated by DFT calculations.

Abstract
![]()
The asymmetric synthesis
of novel 3-substituted isoindolinones
is herein reported. A new cascade reaction was developed that consisted
of the asymmetric nitro-Mannich reaction of suitable α-amido
sulfones designed from 2-formyl benzoates, followed by the in situ cyclization of the adducts. Very high enantioselectivities,
up to 98% ee, and very good yields were obtained in the presence of
the readily available neutral bifunctional organocatalyst derived
from trans-1,2-diaminocyclohexane, which is known
as Takemoto’s catalyst. The investigation of the reactivity
of the obtained products allowed either the selective Boc-deprotection
or reduction of the nitro group, leading to further functionalized
3-substituted isoindolinones without affecting the enantiomeric purity.

Abstract
![]()
A highly
efficient enantioselective inverse-electron-demand aza-Diels–Alder
reaction between aza-sulfonyl-1-aza-1,3-butadienes and silyl (di)enol
ethers has been developed. The presented methodology allows the synthesis
of benzofuran-fused 2-piperidinol derivatives with three contiguous
stereocenters in a highly selective manner, as even the hemiaminal
center is completely stereocontrolled. Density functional theory (DFT)
calculations support that the hydrogen-bond donor-based bifunctional
organocatalyst selectively triggers the reaction through the ipso,α-position
of the dienophile, in contrast to the reactivity observed for dienolates
in situ generated from β,γ-unsaturated derivatives. Moreover,
the calculations have clarified the mechanism of the reaction and
the ability of the hydrogen-bond donor core to hydrolyze selectively
the E isomer of the dienol ether. Furthermore, to
demonstrate the applicability of silyl enol ethers as nucleophiles
in the asymmetric synthesis of interesting benzofuran-fused derivatives,
the catalytic system has also been implemented for the highly efficient
installation of an aromatic ring in the piperidine adducts.

Abstract
A highly stereoselective access to 3-sulfinyl-substituted isoindolinones has been achieved by a tandem organocatalytic addition/cyclization reaction of 2-carbobenzyloxy-N-tosylbenzylidenimine with thiols and succeeding diastereoselective oxidation with MCPBA. First, enantioenriched isoindolinone N,S-acetals have been obtained through a dynamic kinetic asymmetric transformation induced by a bifunctional chiral thiourea organocatalyst. In turn, the newly created carbon stereocenter enabled a high diastereocontrol in the subsequent sulfoxidation. Based on DFT calculations, a theoretical rationale for the stereoselectivity of the oxidation reaction is also provided.

Abstract
A new asymmetric organocatalyzed intramolecular aza-Michael reaction by means of both a chiral auxiliary and a catalyst for stereocontrol is reported for the synthesis of optically active isoindolinones. A selected cinchoninium salt was used as phase-transfer catalyst in combination with a chiral nucleophile, a Michael acceptor and a base to provide 3-substituted isoindolinones in good yields and diastereomeric excesses. This methodology was applied to the asymmetric synthesis of a new pazinaclone analogue which is of interest in the field of benzodiazepine-receptor agonists.
