Carbon-Carbon Bond Formation via Intramolecular Cycloadditions: Use of the Thiocarbonyl Ylide Dipole in anhydro-4-Hydroxythiazolium Hydroxides

Article abstract of DOI:10.1021/jo00266a016

The mesoionic systems resulting from the introduction of 2-(allyloxy)phenyl substituents into the 2-, 3-, and 5-positions of anhydro-4-hydroxythiazolium hydroxide undergo intramolecular cycloaddition under different reaction conditions, the ease of cycloa
