A convenient regioselective synthesis of spirooxindolinopyrrolizidines incorporating the pyrene moiety through a [3 + 2]-cycloaddition reaction

Abstract A facile one-pot synthesis of spirooxindolinopyrrolizidines incorporating the pyrene moiety was accomplished in good yields through a 1,3-dipolar cycloaddition reaction of 3-aryl-1-(pyren-1-yl)prop-2-en-1-one derivatives with in situ-generated azomethine ylides.
