This invention describes reagent precursors and methods for chemical and biochemical reactions. These reagent precursors that can be activated in solution upon irradiation to generate reagents required for the subsequent chemical reactions. Specifically, photogenerated reagents (PGR) are useful for controlling parallel combinatorial synthesis and various chemical and biochemical reactions.

The transition metal-catalyzed reductivecyclization of o-nitrostyrene in the presence of carbonmonoxide (CO) has been developed to be a general synthetic route to an indole skeleton, wherein CO was used as a reductant to deoxidize nitroarene into nitrosoarene and/or nitrene with CO2 release, but the selective insertion of CO into the heterocyclic product with higher atom economy has not yet been

A novel approach toward the synthesis of sterically hindered o-aminophenols has been achieved by a formal aryne insertion into hydroxyindolinones. This transformation offers a rapid and efficient entry to diverse o-aminophenol scaffolds under mild transition-metal-free conditions. The reaction involves the addition of hydroxyindolinones to arynes followed by a chemo- and regioselective [1,3]-rearrangement. Furthermore, the reactions of N-hydroxyindoles and arynes were found to provide the C3-aryl indole products via an alternative [3,3]-rearrangement pathway.
