Popis:	A templated Staudinger–aza-Wittig tandem reaction selectively affords in one step a monocellobiosyl[bis(ureido)]diazacrown cryptand and a bis(cellobiosyl)tetraureido[bis(diazacrown)] cryptand. Formation of each type of cryptand was under control by Na+ or Cs+ template effect. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
