Abstract

We have developed an efficient synthetic method for the production of substituted tetrahydropyrano[2, 3-c]pyrazoles using (E)-2-nitro-1,3-enynes, 1-aryl-3-substituted pyrazolones and methyl vinyl ketone. The sequential, one-pot reaction proceeded smoothly to give the desired products in high to excellent yields and stereoselectivities in the presence of a quinine-derived squaramide organocatalyst.
