A new tricyclic ring and a nitrogen–sulfur analogue of the tri-pentagon bowl: cycloaddition reactions of the unstablised 1,3,4-thiadiazolium-3-methanide 1,3-dipole: steric influences on the endo-effect: substituted pyrrolo[2,1-b]-1,3,4-thiadiazole systems: azolium 1,3-dipoles

1,3,4-Thiadiazolium-3-methanide 1,3-dipole 6 and the 2,5-diphenyl and 2,5-dimethyl derivatives, 4 and 5, were generated at −60 °C in dichloromethane. Cycloaddition reactions with substituted alkenes gave many new derivatives of the pyrrolo[2,1-b][

ChemInform Abstract: A New Tricyclic Ring and a Nitrogen-Sulfur Analogue of the Tri-pentagon Bowl. Substituted 5,6,7,7a-Tetrahydropyrrolo [2,1-b]-1,3,4-thiadiazole-endo-6,7-dicarboxyimides

The first examples of a bowl-shaped tricyclic nitrogen-sulfur analogue of the tri-pentagon bowl are reported; substituted 5,6,7,7a-tetrahydropyrrolo[2,1-b]-1,3,4-thiadiazole-endo-6,7-dicarboxyimides are synthesised by a relatively simple route.
