Reaction Conditions:
with potassium carbonate in acetonitrile at 92; for 2 h;Microwave irradiation;
Steps:
Microwave-assisted synthesis of 5,11,17,23,29,35-hexa-tert-butyl-37,38,39,40,41,42-hexakis-[(ethoxycarbonyl)methoxy]calix[6]arene (1)
In 5 cm3 of acetonitrile, 0.39 g of 4-tert-butylcalix[6]arene(5,11,17,23,29,35-hexa-tert-butylcalix[6]arene-37,38,39,40,41,42-hexol) (0.40 mmol), 1.01 g of 2-bromoethylacetate (6.03 mmol), and 1.67 g of potassiumcarbonate (12.06 mmol) were suspended and stirred for 2h at 92°C while exposed to microwave radiation. Theorganic solvent was evaporated and the reaction mixturewas then extracted with dichloromethane/water. Thedichloromethane layer was collected and evaporated, andthe residuewas recrystallized from absolute ethanol to give560 mg of compound 1 (94% yield). NMR and IR spectracorrespond to the literature data (27).
