Stereoselective synthesis of spirocyclic nitronates by SnCl4-promoted reaction of nitroalkenes with C-2 substituted 4-methylidene-1,3-dioxolane
摘要:
SnCl4-promoted [4 + 2] cycloaddition of beta-nitrostyrenes to 4-methylidene-1,3-dioxolane provides stereoselective synthesis of spirocyclic nitronates. 2-Nitrovinyl benzoate under the same conditions produces delta-substituted nitrodiene as a single E,E-isomer.
