Abstract:
A novel synthetic protocol for the assembly of pyrrolo[1,2-a]indolenine has been developed through a highly diastereoselective [3+2] annulation of 1,1-cyclopropanediesters with indolenines in the presence of catalytic Yb(OTf)3. This new strategy allows a facile construction of the multicyclic system with the flexible variation on the substituents in high yields (up to 86%) with excellent diastereoselectivities (>20:1 dr) in most cases.

Abstract:
2-Substituted indoles may be directly transformed to 3,3-dialkyl indolenines with trichloroacetimidate electrophiles and the Lewis acid TMSOTf. These reactions provide rapid access to complex indolenines which are present in a variety of complex natural products and medicinally relevant small molecule structures. This method provides an alternative to the use of transition metal catalysis. The indolenines are readily transformed into spiroindoline systems which are privileged scaffolds in medicinal chemistry.

Abstract:
Trichloroacetimidates function as effective electrophiles for the selective C3-alkylation of 2,3-disubstituted indoles to provide 3,3′-disubstituted indolenines. These indolenines are common synthetic intermediates that are often utilized in the synthesis of complex molecules. Effective reaction conditions utilizing Lewis acid catalysts have been determined, and the scope of the reaction with respect to indole and imidate reaction partner has been investigated. This chemistry provides an alternative to base promoted and transition-metal-catalyzed methods that are more commonly utilized to acce

Abstract:
Heptamethine cyanine dyes are attractive compounds for imaging purposes in biomedical applications because of their chemical and photophysical properties exhibited in the near-infrared region. A series of meso amino-substituted heptamethine cyanine dyes with indolenine, benz[e]indolenine and benz[c,d]indolenine heterocyclic moieties were synthesized and their spectral properties including fluorescence quntum yield were investigated in ethanol and ethanol/water mixture. Upon substitution with amines, the absorption maxima of the dyes shifted to the lower wavelength region (~600 nm), showed lar

Abstract:
Our group recently discovered and developed a diastereoselective reaction yielding C3-quaternary indolenines from the combination of α,β-unsaturated N-aryl ketonitrones and mono- or di-activated alkynes in toluene at 80 °C. This reaction builds a high level of complexity in a single step, and the C3-quaternary indolenines produced show promise as precursors to indole-containing molecules of biological and medicinal interest. However, we found our substrate scope was limited by the methods available for the synthesis of the α,β-unsaturated N-aryl ketonitrones necessary for the reaction. As a
