A selectively deprotectable triazacyclophane scaffold for the constructionof artificial receptors

[GRAPHICS] The synthesis of a triazacylclophane scaffold bearing a set of selectively removable protecting groups is described, This versatile scaffold, which ca n be linked to a solid support, allows the attachment of three different si de chains and can therefore be used for the combinatorial synthesis of libr aries of artificial receptor molecules of high structural diversity.
