A carbene-catalyzed enantio- and diastereoselective [2 + 4] cycloaddition reaction is developed for quick and efficient access to structurally complex multicyclic pyrano[2,3-c]pyrazole molecules. The reaction tolerates a broad scope of substrates bearing various substitution patterns, with the multicyclic pyrano[2,3-c]pyrazole products afforded in generally good to excellent yields and optical purities

3-Aryl-2-chloropropanal was obtained by the reaction of arenediazonium chlorides with acrolein in the presence of copper(II) chloride. N-Aryl(2-pyridyl)-5-(R-benzyl)-1,3-thiazole-2-amines were formed in high yield by the reaction of these aldehydes with aryl-and 2-pyridylthioureas. The same compounds were obtained by the reaction of 5-(R-benzyl)-1,3-thiazole-2-amines with aniline.
