摘要：

Consecutive base-catalysed reactions of calix[4]arene with the ditosylates of two different polyetherdiols result in the relatively efficient production of an unsymmetrical calixbiscrown-6 which, after reduction of an ethoxycarbonyl substituent to an hydroxymethyl group, has been characterised structurally by a room-temperature, single crystal X-ray study of its chloroform solvate. Crystals of (4), C53H62O13 . similar to 0.57CHCl(3), are triclinic, P (1) over bar, a 18.95(3), b 12.394(9), c 11.756(7) Angstrom, alpha 106.93(5), beta 101.77(8), gamma 94.63(8)degrees, Z = 2; R was 0.088 for 2231 'observed' (I > 3 sigma(I)) diffractometer data.
