General experimental Starting materials were purchased from commercial suppliers and used without further purification or were prepared by literature procedures. Melting points were measured on a Meltemp apparatus in open capillary tubes and are uncorrected. IR spectra were recorded on a JASCO FT/IR 4100 spectrometer and are reported in cm-1. NMR spectra were measured on Bruker spectrometers operating at 400 or 600 MHz for 1H and 100 or 125 MHz for 13C using D2O, or DMSO-d6 as solvents. Chemical shifts (δ) are referenced relative to the residual resonances for HOD (4.80 ppm) and DMSO-d6 (2.50 ppm for 1H, 39.51 ppm for 13C). Mass spectrometry was performed using a JEOL AccuTOF electrospray instrument (ESI). ITC data was collected on a Malvern Microcal PEAQ-ITC instrument and analyzed using the software provided by the vendor.
