Aryl aldehydes and chiral -amino acids were treated (1) in the presence of H3PO4 in ethanol at 80 degrees C for 24 h, and (2) in the presence of K2CO3 under ultrasonic conditions in an aqueous ethanol medium within 5 min with yields reaching up to 96%. The results showed that the presented methodology under ultrasonic conditions was effective, practical, and eco-friendly compared to that using an acidic medium. The corresponding asymmetric Schiff bases were synthesized for the first time, and were characterized by H-1 and C-13 nuclear magnetic resonance and infrared spectroscopy and high-resolution mass spectrometry.en10.1002/jccs.201600094info:eu-repo/semantics/closedAccessChiralityAmino acidsSchiff basesAldehydesArticle639808817WOS:000385373600009Q3Q4
