Biginelli product to the left The actual Hd atoms in the Biginelli product have slightly different chemical and physical properties. As a result, they create two separate 1H-NMR signals and display a two-bond coupling (2 JHH). Identify the cause of these two Hd atoms having slightly different chemical and physical properties by making explicit reference to the Biginelli product. Biginelli product to the left.
