Cyclotriveratrylenes

Cyclotriveratrylene (CTV) is an organic compound with the formula [C6H2(OCH3)2CH2]3. It is a white solid that is soluble in organic solvents. The compound is a macrocycle and used in host–guest chemistry as a molecular host. See more The compound can be synthesised from veratrole alcohol upon acid catalysis. Operating via the same intermediates, an alternative synthesis involves the acid-catalyzed reaction of veratrole and formaldehyde. … See more CTV has a bowl shaped conformation, giving the molecule C3 symmetry. The ether groups are situated at the upper rim, but in contrast a crown ether typically do not interact with guests. The compound is related to calixarenes in terms of its host–guest … See more CTV was first synthesised by Gertrude Robinson in 1915 but misdiagnosed as the dimer. In 1965, Lindsey identified the correct structure and coined cyclotriveratrylene … See more
