functionalized acylborons are prepared by ozonolysis of alkenyl MIDA boronates. The first synthesis of α-amino acylborons, including the enantiopure alanine-type acylboron was achieved using this method. The products are essential for protein–protein conjugation by potassium acyltrifluroborate ligation. Oligopeptide synthesis using α-amino acylborons proceeded in dilute aqueous medium and the alanine-type acylboron
