Isolation of two conformationally frozen isomers of a bridged calix[6]arene
Two conformationally frozen isomers of a 1,4-bridged calix[6]arene, one of which is a cone conformer while the other adopts a 1,2,3-alternate conformation, have been isolated by silica-gel chromatography. The interconversion between them was not observed even after healing either of them at 120 degr...

Summary: | Two conformationally frozen isomers of a 1,4-bridged calix[6]arene, one of which is a cone conformer while the other adopts a 1,2,3-alternate conformation, have been isolated by silica-gel chromatography. The interconversion between them was not observed even after healing either of them at 120 degrees C. |
