Supplementary tables, figures, detailed experimental procedures, and additional analytical data (e.g. NMR, MS) can be found in the supporting information file. Unless indicated differently, all chemicals used were of reagent grade, purchased from commercial sources, and used as received. All solvents used in the reactions were obtained from commercial sources and used as received. Reactions were carried out under inert atmosphere (N2) using flame-dried glassware and anhydrous solvents, if not indicated otherwise. Detailed information on the reaction conditions, experimental procedures, instruments used, and the characterization of all newly synthesized compounds including 1and 2-D NMR spectral data can be found in the supporting information.
