, p. 762 - 765 (2017)
An enantioselective intramolecular dearomative Michael addition of indolyl enones is presented. In the presence of catalytic amount of chiral phosphoric acid, various enantioenriched spiro-indolenines bearing a quaternary stereogenic center were obtained

Selective formylation of free (N-H) indoles at C3 can be achieved by using formylating species generated from hexamethylenetetramine (HMTA) and silica-supported ceric ammonium nitrate (CAN-SiO2). The use of a catalytic amount of this solid-supported reagent was found to be compatible with a range of substituents on the indoles and generated the corresponding products with good yields. A plausible mechanism for the formylation involving an electron transfer process is discussed.

A series of benzofuran-3-one indole phosphatidylinositol-3-kinases (PI3K) inhibitors identified via HTS has been prepared. The optimized inhibitors possess single digit nanomolar activity against p110α (PI3K-α), good pharmaceutical properties, selectivity versus p110γ (PI3K-γ), and tunable selectivity versus the mammalian target of rapamycin (mTOR). Modeling of compounds 9 and 32 in homology models of PI3K-α and mTOR supports the proposed rationale for selectivity. Compounds show activity in multiple cellular proliferation assays with signaling through the PI3K pathway confirmed via phospho-Akt inhibition in PC-3 cells.

A new, general route to the benz[5,6]azepino[4,3-b]indole ring system has been developed via the 1,7-dipolar electrocyclisation reactions of azomethine ylides. A new, general route to the benz[5,6]azepino[4,3-b]indole ring system has been developed via the 1,7-dipolar electrocyclisation reactions of azomethine ylides derived from easily available 3-formyl indole derivatives. The intermediacy of azomethine ylides was shown by the trapping of the proposed α,β:γ,δ-conjugated dipole with N-phenylmaleimide.
