correlation to theoretical 1H and 13C NMR DFT–GIAO (B3LYP/6‐311 + + G**//B3LYP/6‐31G*) calculations. A systematic conformational analysis of these compounds was performed in a two‐step methodology, using PM3 and DFT (B3LYP/6‐31G*) calculations; with good accomplishment and computational time economy. It was observed that intramolecular hydrogen bonding plays a significant role in the conformation of such
