Supplementary Figure 2: 1H NMR spectrum for compound 2
From: Preparative scale and convenient synthesis of a water-soluble, deep cavitand
1H-NMR spectrum (25 °C, DMSO-d6, 600 MHz) of the compound 2. The characteristic methine peak and the corresponding atoms are marked with the green arrows. The material may contain traces of residual Et2O, which does not interfere with the next step.
