Tripeptide aldehydes, such as Z-Leu-Leu-Leu-H (MG-132), are an important class of compounds due to their biological activity. A new, generalmethod for the synthesis of tripeptide aldehydes based on the multi-component Ugi reaction was developed. A careful choice of isocyanides makes it possible to obtain tripeptide precursors whose functionalization led to target structures. This method can be used
