Gold-Catalyzed Intramolecular Hydroamination of o-Alkynylbenzyl Carbamates: A Route to Chiral Fluorinated Isoindoline and Isoquinoline Derivatives
2013
Enantiomerically pure fluorinated isoindoline and dihydroisoquinoline scaffolds have been prepared through a diastereoselective addition of fluorinated nucleophiles to Ellman’s N-(tert-butanesulfinyl)imines followed by a sequence of Sonogashira cross-coupling/gold(I)-catalyzed cycloisomerization of the corresponding carbamate. A more favored 5-exo-dig mechanism was observed mainly due to an electronic effect of the fluorinated group.
2-[(1-Methyl-1H-pyrrol-2-yl)carbonyl-meth-yl]isoindoline-1,3-dione.
2009
The asymmetric unit of the title compound, C15H12N2O3, contains two almost identical molecules forming an nearly C2-symmetric dimeric pattern. The dihedral angles between the pyrrole ring and the phthalimide unit are 82.95 (8) and 86.57 (8)° for the two molecules. Within such a dimer, the phthalimide units of the two molecules form a dihedral angle of 1.5 (5)°.
1,1,3,3-Tetraethyl-5-nitroisoindoline

The title compound, C16H24N2O2, previously obtained as a yellow oil, exhibits a rather low melting point close to room temperature 297–298 K). In the molecule, the isoindoline ring system is approximately planar and coplanar to the nitro group, forming a dihedral angle of 5.63 (15)°. In the crystal, only weak N—H...O and C—H...π interactions are observed, linking molecules into chains parallel to the [101] direction.

Title compounds are prepared in enantiomerically pure form by the diastereoselective addition of fluorinated nucleophiles to N-(tert-butanesulfinyl)imines (I) followed by a sequence of Sonogashira cross-coupling/gold(I)-catalyzed cycloisomerization of the corresponding carbamate.
Farinomalein derivatives from an unidentified endophytic fungus isolated from the mangrove plant Avicennia marina
2012
Five farinomalein derivatives including three new compounds, farinomaleins C–E (3–5), and one new isoindoline congener (6) were isolated from an unidentified endophytic fungus obtained from the inner tissues of healthy leaves of the mangrove plant Avicennia marina from Oman. The structures of the new compounds were unambiguously elucidated on the basis of their mass, as well as one and two dimensional NMR spectroscopic data.

Treatment of trans-[PtCl2(NCR)2] 1 (R = Me (1a), Et (1b), o-ClC6H4 (1c), p-ClC6H4 (1d), p-(HCdouble bond; length as m-dashO)C6H4 (1e), p-O2NC6H4CH2 (1f)) with 1,3-diiminoisoindoline HNdouble bond; length as m-dashCC6H4C(NH)double bond; length as m-dashNH 2 gives access to the corresponding (1,3,5,7,9-pentaazanona-1,3,6,8-tetraenato)Pt(II) complexes [PtCl{NHdouble bond; length as m-dashC(R)Ndouble bond; length as m-dashC(C6H4)NCdouble bond; length as m-dashNC(R)double bond; length as m-dashNH}] 3a–f, in good yields (65–70%). The reaction of trans-[PdCl2(NCMe)2] 4a with 2 furnishes (1,3,5,7,9-pentaazanona-1,3,6,8-tetraenato)Pd(II) complex [PdCl{NHdouble bond; length as m-dashC(Me)Ndouble bond…
