Organocatalytic Regio- and Enantioselective (3+3)-Annulation of 2-(4H-Benzo[d][1,3]oxazin-4-yl)acrylates with 2,4-Dihydro-3H-pyrazol-3-ones
A chiral sulfonamide-phosphine catalyzed regio- and enantioselective (3 + 3)-annulation of 2-(4H-benzo[d][1,3]oxazin-4-yl)acrylates with 2,4-dihydro-3H-pyrazol-3-ones has been established, affording a wide range of such 1,4,5,6-tetrahydropyrano [2,3-c]pyrazole-containing carboxylates in generally hi...
