AbstractA 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
Reaction of aromatic N-oxides with dipolarophiles. XI 1,3-Dipolar cycloaddition reaction of pyridine N-oxides with tosyl isocyanate and one-pot synthesis of 2-oxooxazolo(4,5-b)pyridine derivatives.
