The first catalytic asymmetric homo-1,3-dipolar cycloadditions of azomethine ylides have been established via SPINOL-derived chiral phosphoric acid-catalyzed pseudo four-component reactions of aldehydes and 2-aminomalonates, resulting in the stereoselective construction of chiral imidazolidine scaffolds with two stereogenic centers in generally high yields and with good stereoselectivities (up to 81%
